Color digital sketch of Lady Seraphine Duskveil, an ancient vampire noble, reclining on a throne carved from black stone and bones. Her flowing crimson gown clings to her lithe figure, a deep slit revealing pale, flawless legs splattered with faint traces of blood. A dark velvet choker adorned with a blood-red ruby encircles her neck. Her piercing, hypnotic golden eyes gleam from beneath raven-black hair cascading like ink. Gothic arches loom behind her, lit only by flickering candles. Medieval vibe with 70s dark fantasy influences. Hyper detailed. Intricate detail. Dramatic brush strokes. Subtle asymmetry. Visible sketch lines. Rich textures with bold shadows. Soulful. The lines vary in thickness. Beautiful, detailed shading with raw, expressive imperfections. Areas left rough or unfinished for a haunting effect.
