How to Get Great Results
- Step 1
Set a clear art direction
Open with style (‘dark fantasy illustration’, ‘photoreal portrait’, or ‘painterly concept art’) and define lighting and palette.
- Step 2
Use ControlNet for composition
When available, apply pose or depth guidance to lock framing, then iterate on wardrobe and background details.
- Step 3
Leverage image‑to‑image
Start from a rough sketch or prior render to preserve composition while changing style, materials, or mood.
- Step 4
Iterate in small steps
Change only one or two variables per run (pose, palette, camera) to converge on a look quickly.
Example Prompts
Fantasy character portrait, half‑elf battlemage with silver filigree armor, moody rim light, 85mm lens, f/2.0, intricate fabric and metal detail
Ancient ruin overgrown with ivy, misty morning light, soft volumetrics, mossy stone, cinematic wide shot, grounded color grade
Rogue’s toolkit flat lay: lockpicks, wax seals, velvet pouch, tarnished silver coins, top‑down studio light, crisp edges, realistic materials
Painterly concept frame of a cliffside citadel at dusk, warm lanterns against cool twilight, sweeping clouds, dramatic composition
