(Masterpiece, best quality, ultra-detailed, professional photoshoot, precision lighting:1.3),
1girl, solo, Ruki (original character), 18-year-old young woman, human face,
deep black glossy long hair (specifically deep black to prevent wash-out),
glossy and moist lips with lip gloss, seductive expression, looking over her shoulder with a teasing look at the camera,
Outfit (Seductive Black Style, exactly as before):
- Backless halter-neck sleeveless top with a deep open back and bow tie, revealing her smooth back and shoulders.
- Matching tight skirt with side cutouts, black high heels.
Glowing blue-purple tribal dragon tattoos vividly glowing on both arms.
Composition & Pose (EXACTLY AS BEFORE, ON A CLASSIC CAR):
- Sitting casually on the glossy painted bonnet of a classic open-wheeled sports car (Caterham Super Seven), crossing her legs gracefully.
- The character twists her upper body slightly to look back at the viewer, beautifully emphasizing her open back and side-cutout silhouette against the car body.
Car Exact Shape & Color Specification (HALATION CONTROL):
- The car is a classic Caterham Super Seven with its distinct shape: a vertical chrome grille, large round headlights integrated into the cycle fenders, a leather strap running across the bonnet, and a small upright windscreen.
- The car's bodywork is a rich, deep, glossy CANDY YELLOW (specific color depth) with a luxurious wet-look finish, utilizing controlled lighting to create deep reflections and avoid washed-out highlights and halation.
Lighting (Crucial for Black Hair):
- Soft, diffused studio lighting from the side and rear (rim lighting) to separate her black hair from the background, combined with focused low-key frontal lighting to highlight her face and the car's contours without blinding reflection.
- Dramatic shadows and controlled contrast to maintain atmospheric depth and ensure her black hair remains dark and detailed. Dark grey gradient background to add contrast.
