Night Yacht Backless Elegance

Strictly preserve identity 1:1 based on the uploaded photo: facial features, proportions, age, eye shape, nose, lips, jawline, skin texture, and eye color; no idealization. Night cinematic photograph on a luxury yacht. A young woman stands with her back turned at half-turn by the railing, gracefully looking back over her shoulder, gaze cast downward, one hand raised to her face, long hair blowing in the wind. She is wearing a form-fitting white backless dress with thin straps and a textured skirt. Even skin tone, long eyelashes, nude smokey eyes, matte dusty pink lips. In the background, a night city skyline with bright skyscrapers and reflection of lights in the water. High-contrast black and white processing, deep black shadows, bright highlights on the water, light film grain, paparazzi-style flash, high contrast, editorial luxury aesthetic, ultra-realism, maximum detail, vertical format 9:16.
