Luxury Billionaire Portrait in a Night Penthouse

Using the uploaded photo, create a photorealistic 4:5 luxury billionaire-style portrait of the same man in a modern penthouse at night. KEEP — Preserve the person's recognizable facial identity from the uploaded photo. Keep the original face shape, forehead width, cheekbone placement, jawline, chin, nose bridge and tip, lip shape, eyebrow position, eye shape and natural eye colour unchanged. Retain the original skin tone, visible pores, fine lines, natural skin texture and facial asymmetry. Keep the original hairline, hairstyle, facial hair and hair colour. Preserve the person's real body proportions, neck width and shoulder structure. Do not reshape the face to fit the luxury styling. CHANGE — Dress him in a tailored charcoal-grey suit jacket with a fine wool texture, structured shoulders and clean lapels. Add a black silk shirt with a subtle natural sheen and an understated silver metal wristwatch. Position him beside a floor-to-ceiling penthouse window, framed from the chest up. His right hand gently adjusts the opposite shirt cuff near his waist, remaining anatomically natural and proportionate. His shoulders stay relaxed, chin slightly raised and eyes directed towards the camera. SCENE — Set the portrait inside a contemporary high-rise penthouse at approximately 10 PM. A distant city skyline with scattered golden and cool-white lights sits behind the glass. Keep the buildings softly blurred while retaining a few recognizable window-light patterns. Use dark architectural surfaces and restrained reflections without adding distracting furniture or decorative objects. LIGHT — Use a soft, neutral-white key light from the front-left, illuminating both eyes and preserving natural skin colour. Add warm reflections from the distant city lights and a subtle steel-blue rim light along the opposite shoulder. Window reflections must remain faint and physically believable. CAMERA — Use an 85mm portrait lens at f/1.8, with the camera at chest height and focused precisely on the eyes. Maintain natural facial perspective, realistic hand proportions and shallow depth of field. GRADE — Apply a refined cinematic grade with charcoal blacks, cool steel-blue shadows, restrained golden highlights and realistic skin tones. Keep contrast controlled so suit details remain visible in the shadows. OUTPUT — Vertical 4:5 aspect ratio, 2048 × 2560 pixels or the closest available high-resolution setting. DO NOT slim the face, whiten the skin, change eye colour, smooth the skin into plastic, alter body proportions, invent jewellery or tattoos, distort the hands, add text or watermarks, or replace the person's identity.
