3D Letter Neon

Create a hyper-realistic 4:5 full-body portrait of the same man, preserving his exact face, hairstyle, and beard. He wears a maroon sweater, black jeans, and white sneakers, standing confidently with hands in pockets. Giant outlined 3D letters "JACK" glow behind him in warm orange and white neon, surrounded by dark smoky haze and a glossy reflective floor. Dramatic cinematic lighting, sharp details, premium poster style, 4K ultra HD, no watermark. 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.
