Create a moody late-night portrait of an adult woman sitting on the damp floor of an old Japanese restroom. Tight vertical composition, slightly high-angle view, candid framing, body angled diagonally, with one soft thigh prominent in the foreground. She has a petite hourglass figure, broad feminine shoulders, full natural bust, narrow waist, rounded hips, plush thighs. She wears an oversized charcoal-black blazer, a rumpled white collared shirt, a loosened narrow black tie, short black bottoms mostly hidden, and simple black thigh garter straps. Her clothes are slightly damp but fully opaque. She looks visibly tipsy and drowsy: heavy half-lidded unfocused eyes, flushed cheeks and nose, parted lips with a small playful tongue-out expression, sleepy loose posture, head resting lazily against the wall. The restroom is old, cold, wet, and deserted, with blue-green tiles, condensation, puddles, subtle reflections, damp walls, and faint mist in the air. Lighting is dim dirty amber tungsten mixed with a small amount of cold desaturated blue light, creating deep teal-black shadows and a quiet 3AM melancholy. Stylized semi-realistic Japanese illustration, moody josei editorial aesthetic, soft painterly anime realism, old 35mm softness, fine analog grain, slight halation, muted low-saturation colors. No bright clean bathroom, no neon cyberpunk, no glamorous studio lighting, no glossy CGI.
