Midnight Luxury Yacht Portrait at Blue Hour

Using the uploaded photo, create a photorealistic luxury lifestyle portrait of the same person relaxing on the rear deck of a black luxury yacht during blue hour, with a deep navy ocean and an illuminated coastline behind them. Use a vertical 4:5 composition. KEEP — Preserve the person's exact facial identity and recognizable face structure, including forehead proportions, eyebrow shape and placement, original eye shape and colour, nose bridge and tip, lip shape, cheek volume, cheekbones, jawline, chin, ears, facial width, and natural asymmetry. Retain the original skin tone, visible pores, fine skin texture, natural marks, and authentic age. Preserve the original hairline, hair texture, hairstyle characteristics, and facial hair wherever visible. Maintain the person's existing body proportions, shoulder width, neck, and natural posture. Do not substitute a generic model's face. CHANGE — Dress the person in a black open-collar silk-blend shirt with subtle sheen, realistic draping, and natural creases around the elbows. Add tailored ivory trousers with a fine woven texture and a brushed-steel wristwatch. Position the person beside a polished yacht railing, with one hand resting naturally on the metal and the torso turned slightly toward the ocean. Keep the expression relaxed and the pose physically comfortable. Add no chain unless one is visible in the uploaded photo or explicitly requested. SCENE — Place the person on the yacht's aft deck shortly after sunset. Include brushed-metal railings, dark teak decking, cream outdoor cushions, and a distant coastline dotted with warm lights. Keep the coastline softly blurred while retaining recognizable yacht details. Show small ocean ripples reflecting scattered blue and amber highlights. LIGHT — Use cool blue ambient light from the open sky and a soft, warm practical light from the yacht's deck fixtures. Illuminate the face from the front at a slight three-quarter angle so facial features remain readable. Keep skin highlights neutral and consistent with the surrounding environment. CAMERA — Shoot with an 85mm portrait lens at f/2.0, camera positioned at chest height. Use natural perspective, controlled background compression, and sharp focus on the eyes. GRADE — Apply deep navy shadows, restrained amber highlights, natural skin tones, moderate contrast, and a subtle cinematic film finish. Avoid crushed blacks and excessive blue tint on the face. OUTPUT — Generate a vertical 4:5 portrait at 8K resolution, with realistic skin detail, fabric texture, reflections, and natural anatomy. DO NOT slim the face, whiten the skin, change eye colour, smooth skin into plastic, alter body proportions, invent tattoos or jewellery, distort hands, or replace the person's identity.
