The six parts together

A painted woman with grey-streaked curls under a shiny hood, in a patched coat with brass toggles, holds a pole upright in a boat on a canal at dawn

Portrait of a halfling river smuggler in her forties. Sun-browned skin, a small scar through her upper lip, grey-streaked curly hair under an oilcloth hood, a patched waxed coat with brass toggles. She leans on a barge pole and looks past the viewer. Dawn mist on a canal behind her, low warm light from the left. Waist-up, 85mm portrait framing. Painterly fantasy illustration with visible brushwork.

Two words against six parts

A wizard in a blue pointed hat and a robe with moons and stars holds a staff with a glowing crystal in a stone alley at night
Two words · 1ka wizard
A painted old man in a holed blue robe mends a net by candlelight in a houseboat cabin, with a heron awake on the shelf and moonlit water in a round window
A full prompt · 1kAn old hedge wizard mends a fishing net by candlelight. Ink-stained fingers, a moth-eaten blue robe, a heron asleep on the shelf behind him. Inside a cramped houseboat cabin. Warm candle light, with cool moonlight from a round window. Medium shot from slightly above. Oil painting with soft edges.

The wanted poster at 1k and at 2k

The wanted poster prompt at the two size steps.

The wanted poster at 1k: the same words, with REWARD and 500 GOLD on two lines in larger letters
1k · 7 gold
A wanted poster on a wooden post with the words WANTED, Brannoc Vale, for the theft of the Tollkeeper's Seal, and REWARD 500 GOLD, and an ink sketch of a dwarf with an eye patch and a braided beard
2k · 17 gold

The lettering is right at both sizes, and the long line stays on one line. At 1k the reward went onto two lines in larger letters, and the dwarf has a scarred eye in place of the patch.

The battle map at 1k and at 2k

The battle map prompt at the two size steps.

The battle map at 1k: the same layout, with the barrels in two rows
1k · 7 gold
A flat top-down cellar map that fills the frame: a broken staircase in the north-west corner, barrels along the south wall, green water in the east half and a rowboat tied to a stone pillar
2k · 17 gold

The same flat layout at both sizes, with everything in its place. The barrels are in two rows at 1k and in one row along the wall at 2k.

What else to know

The finish is the part that makes it paint. We built the portrait prompt one part at a time. The five pictures before the finish were photos, or close to one. “Painterly fantasy illustration with visible brushwork” gave clear brush strokes, in both runs.

A short prompt gets a smooth picture. “a wizard” gave a wizard in a stone alley at night, smooth and close to a photo.

Use compass words to place things. North-west corner, east half, south wall. The battle map put all three where the prompt said, at both sizes.

Lettering stays on its line. Three lines on the wanted poster, all spelled right at 1k and at 2k. The long line did not wrap.

A light direction can be lost. “lantern light from below” gave no lantern and even light, in both token runs.

Small states can get lost. The heron was to be asleep. It came out awake.

It adds the marks of the kind. The bugbear got tusks and pointed ears in both runs. Neither was in the prompt.

Size words need something to measure against. A halfling alone in the frame reads as human.

Six table jobs

The same six jobs go to every model, so you can compare one model with the next.

Character portrait

  • Name things you can see.Skin, a scar, hair, a hood, a coat. The scar is hard to see in this run and clear in a second run. The other four came out both times.
  • Say where the light comes from.“low warm light from the left”
  • Give the crop and the lens.“Waist-up, 85mm portrait framing.”
A painted woman with grey-streaked curls under a shiny hood, in a patched coat with brass toggles, holds a pole upright in a boat on a canal at dawn

Portrait of a halfling river smuggler in her forties. Sun-browned skin, a small scar through her upper lip, grey-streaked curly hair under an oilcloth hood, a patched waxed coat with brass toggles. She leans on a barge pole and looks past the viewer. Dawn mist on a canal behind her, low warm light from the left. Waist-up, 85mm portrait framing. Painterly fantasy illustration with visible brushwork.

3:4 · 1k · 880 × 11847 GoldOpen in studio

The hood, the hair, the patched coat and the toggles are there, in clear brush strokes. She holds the pole and does not lean on it. Nothing in the frame shows her height, so the halfling reads as human.

Token

  • Call it a round game token.“Round game token of a bugbear tollkeeper.”
  • Ask for a ring.“A thick dark bronze ring around the token.”
  • It does not cut the token out.“Nothing outside the ring” gave a white ground. This model has no Background setting.
A round token of a bugbear with tusks in an iron-banded cap, inside a bronze ring on a white ground

Round game token of a bugbear tollkeeper. Head and shoulders, facing the viewer, heavy brow, an iron-banded leather cap, lantern light from below. A thick dark bronze ring around the token. Painted fantasy style. Nothing outside the ring.

1:1 · 1k · 1024 × 10247 GoldOpen in studio

A clean ring on a white ground. There is no lantern and no light from below, in both runs. He got tusks that the prompt did not ask for. For a cut-out, take the picture to Token Maker.

Battle map

  • Lock the view.“seen from directly overhead with no perspective” gave a flat map.
  • Place things with compass words.“in the north-west corner”, “along the south wall”, “the east half”
  • Ask for one view.“One single view that fills the whole frame.” The map fills the frame, with no title, legend or grid, at 1k and at 2k.
A flat top-down cellar map that fills the frame: a broken staircase in the north-west corner, barrels along the south wall, green water in the east half and a rowboat tied to a stone pillar

Top-down battle map of a flooded cellar under a tavern, seen from directly overhead with no perspective. Flagstone floor. The east half is under knee-deep green water. Stacked barrels along the south wall, a collapsed wooden staircase in the north-west corner, a small rowboat tied to a stone pillar in the water. Even light, hand-painted tabletop map style. One single view that fills the whole frame.

3:2 · 2k · 2512 × 166417 GoldOpen in studio

The staircase, the water, the barrels and the boat on its rope are where the prompt put them, at both sizes.

Item

  • Say it is on its own.“One magic item on its own” gave a plain blue-grey ground.
  • Give the material and one odd detail.“tarnished brass”, “the needle is a sliver of blue ice”
  • The finish words did not give paint here.“Painted fantasy item art, crisp edges.” gave a clean render.
A brass compass with cracked glass, frost and a needle of blue ice, as a clean render on a blue-grey ground

One magic item on its own: a ship's compass of tarnished brass with a cracked glass face. The needle is a sliver of blue ice that sheds faint frost. Three-quarter view, soft light from above. Painted fantasy item art, crisp edges.

1:1 · 1k · 1024 × 10247 GoldOpen in studio

The cracked glass, the ice needle and the frost are all there. The letters on the dial are not compass letters. The ground is plain, not transparent.

Scene

  • Open with the shot.“Wide establishing shot of…”
  • Put something in the foreground.“A mule caravan crosses a causeway in the foreground.”
  • Give the time of day and two colours.“Late afternoon, long shadows, muted greens and rust.”
A row of houses on the spine of a giant's mossy skeleton, with a skull, ribs and an arm, and a mule caravan on a causeway in front

Wide establishing shot of a toll town built along the back of a fallen stone giant. Houses line the spine, rope bridges hang between the ribs, market smoke rises. A mule caravan crosses a causeway in the foreground. Late afternoon, long shadows, muted greens and rust. Painterly fantasy landscape.

21:9 · 1k · 1568 × 6727 GoldOpen in studio

The giant is a mossy skeleton: a skull, ribs, a spine and an arm. Houses line the spine, market stalls stand under the ribs, smoke rises, and the caravan crosses a causeway in front. There are red marks like a signature in both bottom corners.

Handout with lettering

  • Name the thing the words are on.“A weathered wanted poster nailed to a wooden post.”
  • Give each line its place, and its words in quotation marks.“Heading in heavy black printed letters: "WANTED".”
  • “One line of text” is kept.The long line stayed on one line, at 1k and at 2k.
A wanted poster on a wooden post with the words WANTED, Brannoc Vale, for the theft of the Tollkeeper's Seal, and REWARD 500 GOLD, and an ink sketch of a dwarf with an eye patch and a braided beard

A weathered wanted poster nailed to a wooden post. Heading in heavy black printed letters: "WANTED". Below the heading, an ink sketch of a one-eyed dwarf with a braided beard. Under the sketch, one line of text: "Brannoc Vale, for the theft of the Tollkeeper's Seal". At the bottom, in large letters: "REWARD 500 GOLD". Torn corners, rain stains, old paper.

3:4 · 2k · 1776 × 236817 GoldOpen in studio

All three lines of lettering are spelled right, each on its own line. The sketch is plain ink, with the eye patch and the braided beard.

Edit with a reference

Say what stays first, then what changes. In the studio, add your picture as a reference before you paste the prompt.

A painted woman with grey-streaked curls under a shiny hood, in a patched coat with brass toggles, holds a pole upright in a boat on a canal at dawn
The reference
The same woman with the same hood, coat and pole in the same boat, now at night in the rain with a lantern on the right
The edit · 7 gold with one reference

Keep her face, her hair, the hood and the coat exactly as they are. Change the time to night. Rain falls. One lantern on the right lights her face. The canal behind her is dark.

From the reference · 1k · 880 × 11847 Gold

The same face, hood and coat, with the pole, the boat and the bridge in the same places. Night, rain and one lantern on the right.
