character: kochou_shinobu, beautiful light, best shadow, color blink, artist se_5eeeee, beautiful colors, visible pencil-like strokes, sketchy and expressive linework, rough painterly anime style, y2k aesthetic, warm-toned shadows, watercolor-like color blending, An illustration in a dark fantasy, gothic anime style, featuring Shinobu Kocho from Demon Slayer, viewed from behind with her purple-and-black butterfly hair ornament. She sits at a dark wooden dressing table with stylized floral arrangements. Before her is an ornate, dark gothic oval mirror. In the mirror's reflection, her own likeness is twisted and macabre, with wide-staring black eyes, a stretched, menacing, wide grin revealing teeth (resembling creepypasta or a horror smile), and a slightly corrupted appearance with the same butterfly hair ornament. The background wall is dark, distressed, and shows shadowy formless wisps, possibly skeletal or phantom hands. The overall color palette is desaturated, with deep purples and blacks dominating, creating a tense, dark, and unsettling atmosphere, like a corrupted mind or a curse. The brushwork is textured and semi-painterly, focused on dark mood. The style should be reminiscent of a corrupted character sheet or official dark-version concept art. The perspective is a 3/4 view from behind.
