Impasto-influenced anime painting with pronounced lighting highlights. Luminous highlights contrast with rich, muted tones, creating a dramatic, emotional surface. Subtle retro flair mix with Western illustration. A glamorous oiran courtesan is depicted in a portrait shot from a slight low angle. She has glossy black hair styled in an elaborate Japanese updo, secured with ornate gold and red kanzashi hairpins. Her slightly brown-tinged black eyes gaze seductively at the viewer, complemented by a sultry, enchanting smile. She wears a luxurious oiran kimono with intricate floral embroidery, wide obi sash, and dangling accessories. Her skin is flawless porcelain with subtle blush. The background is a dimly lit tatami room with shoji screens and hanging lanterns. Dramatic lighting from above casts luminous highlights on her hair and fabrics, contrasting with deep shadows. Rich impasto textures emphasize folds, hair strands, and metallic details. Subtle chromatic aberration and film grain add a retro Western illustration vibe to the emotional, dramatic atmosphere.
