Hyper-Realistic Bodybuilding Gym Portrait ????

Create a photorealistic vertical gym portrait of a heavily muscular young man performing a powerful dumbbell bicep curl, with the same face, hairstyle, aviator sunglasses, pose, body proportions, and overall composition as the reference image. His face skin tone and body skin tone must match perfectly, with natural transitions between face, neck, shoulders, arms, and torso; avoid any difference in color, excessive tanning, artificial orange tones, plastic skin, or overly exaggerated retouching. Use realistic gym lighting with natural highlights on sweat-covered skin, authentic muscle definition and vascularity, detailed skin pores and subtle imperfections, realistic shadows, and a true-camera photographic look. Keep the black “IVANKO 50” dumbbell, dark blue posing trunks with white stripes, gym equipment, blurred person in the background, and “ARNOLD THE OAK” poster; use shallow depth of field, natural color grading, realistic lens characteristics, and documentary-style high-end DSLR photography so the final image looks like an actual photograph rather than an AI-generated render. 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.
