Large 3D Name Sign Portrait

Create a premium, ultra-realistic full-body studio fashion portrait of the uploaded man, preserving his natural facial identity, skin tone, age, hairstyle and existing facial hair. Dress him in a relaxed deep chocolate-brown button-down shirt made from soft brushed cotton with an open collar, rolled sleeves and natural folds, paired with tapered black trousers, clean white low-top sneakers, black rectangular sunglasses and a silver wristwatch. Position him closely beside the installation with relaxed shoulders, ankles casually crossed, one hand inside his trouser pocket and the other holding a second pair of thin-framed sunglasses near his waist. His body faces slightly toward the camera while his head turns naturally toward camera right with a calm, confident expression. To his left, place separate oversized three-dimensional letters vertically stacked in open space, spelling “NAME” exactly from top to bottom. Each letter must have a smooth, continuous warm-white illuminated front face with thick black extruded sides, supported invisibly above a minimal black floor base. Do not use a backing panel, frame, column or visible marquee bulbs. Make the complete letter installation approximately the same height as the subject. Use a seamless deep-black studio background and dark reflective floor. Let the illuminated letters act as the dominant warm side light, casting a soft amber glow across the subject, outlining his clothing and creating a concentrated reflection beneath the installation. Add only subtle frontal fill to preserve natural facial detail and rich shadows. Eye-level 50mm perspective, realistic proportions, cinematic low-key editorial photography, clean composition without additional text or logos, 4:5 or 3:4 aspect ratio. Letters vertically stacked, No gap between the letters. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
