Retro Powerhouse — Vintage Bodybuilder Portrait

Use the uploaded images as references. Create an ultra-realistic, photorealistic gym portrait combining the muscular physique and body composition of the first reference with the face, hairstyle, moustache, short beard, and overall facial appearance of the second reference. Preserve the second reference’s facial characteristics accurately: face shape, eyes, eyebrows, nose, lips, jawline, skin tone, moustache, beard, and distinctive retro hairstyle. The man should have a strong, serious, confident expression and wear gold-framed dark aviator sunglasses. Give him a highly muscular, naturally proportioned body with broad shoulders, massive chest, defined arms, visible veins, chest hair, detailed abdominal muscles, realistic skin texture and subtle sweat. Keep the dark athletic shorts with the light waistband. Set the scene inside a realistic gym with soft warm indoor lighting, shallow depth of field, subtle background blur, neutral walls and faint gym equipment/poster details. Maintain realistic skin pores, sweat highlights, natural shadows, accurate anatomy, DSLR photography quality, high detail, 4K photorealism. Style: realistic human photograph, vintage-retro masculine aesthetic, natural color grading, professional DSLR photography, highly detailed, no cartoon, no illustration, no artificial-looking face, no exaggerated body proportions. 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.
