Create a highly photorealistic, high-resolution full-body mirror selfie of a young model in a modern indoor gym using the uploaded reference image with strict identity lock enabled. His face must be 100% identical to the reference image with absolute preservation of identity. Do not alter facial structure, proportions, bone shape, skin texture, skin tone, eye shape, nose, lips, expression mechanics, age,or any fine facial details. No beauty retouching, no face refinement, no identity blending, and no stylization. The face must be an exact, unmodified match to the reference. His hair is dark brown, styled in a short, tousled, textured cut with loose strands framing his face, appearing natural and realistic. Skin remains natural and realistic with light stubble, matching the reference precisely. His expression is calm, composed, and slightly focused as he looks at the phone screen during the mirror selfie. Maintain a natural, candid demeanor changing facial expression details. He stands with one leg slightly forward in a confident athletic stance, holding an orange iPhone smartphone in his right hand for the mirror selfie and a transparent water bottle filled with blue liquid in his left hand. Outfit details: Fitted short-sleeve white athletic t-shirt White long-sleeve shirt tied around his waist Fitted black athletic shorts White crew socks White athletic sneakers Environment: a clean, modern gym featuring large wall mirrors with a vertical mirror seam in the frame, treadmills, weight machines, rubber gym flooring, and exercise mats. The background should be clear and realistic, with accurate scale and depth. Lighting is bright overhead fluorescent gym lighting, providing even, neutral illumination with minimal shadows and no dramatic contrast. Composition: a casual fitness lifestyle photograph, captured at eye level, with the subject centered in the frame. Emphasize sharp facial detail, realistic clothing textures, accurate reflections, and a clean, modern, casual mood. Apply minimal post-processing, no filters, no style transfer, and maintain strict facial identity lock at all times.
