Lat Spread Portrait for Fit

"A hyper-realistic full-body portrait of an 18 year old gym-fit young man, using the uploaded reference image strictly to keep his real face, facial structure, face shape, hairstyle, and facial features exactly unchanged with zero alteration in ultra-HD detail, preserving natural skin texture, exact facial proportions, and identity accuracy with no beautification, no reshaping, no smoothing, no face swap or identity drift. He has stylish messy hair and a very short ultra-light stubble beard exactly like the reference image, extremely minimal, close-trimmed, clean, subtle and sharp, no thick beard, no long beard, no heavy density, no overgrown facial hair. POSE: Back Lat Spread, locked with zero variation. The subject faces completely away from the camera, feet firmly planted shoulder-width apart on the dark rubber gym floor, both hands placed firmly on the sides of his waist with elbows pushed outward and back to spread his lats into their fullest possible width, the entire back musculature expanding dramatically from a tight narrow waist upward into broad sweeping wings of muscle, every detail of the rhomboids, teres major, rear deltoids, and trapezius rendered in cinematic sharp relief. His head faces slightly right as if acknowledging the mirror in front of him, neck thick and defined, the back of his hair styled naturally. He is shirtless, wearing black modern fitted sweatpants sitting low on his hips, the waistband revealing the upper dimples of his lower back. Warm amber gym lighting from above and slightly to the right traces every muscle contour in deep shadow and bright highlight, the sweat across his upper back and shoulders catching the light in a realistic organic sheen. The background is a premium gym interior facing a large floor-to-ceiling mirror where his front reflection is softly visible adding a layered depth dimension to the image, metallic equipment and dark rubber flooring visible in blurred bokeh on either side. Shot on Sony A7R IV with an 85mm lens at f/1.8, directional overhead amber lighting, deep muscle shadow rendering, 8K ultra-HD photorealistic quality. Ultra-realistic photography style, natural skin texture with visible pores, dark warm cinematic physique photography color grading, professional bodybuilding editorial finish. Aspect ratio: 3:4 vertical. Negative prompt: blurred face, face distortion, identity change, face swap, asymmetry, bad anatomy, extra limbs, low resolution, noise, over-smoothing, plastic skin, cartoon or CGI style, watermark artifacts, unnatural lighting.
