gym fitness photo prompt | powerful cinematic 8K AI

Create an ultra-realistic 8K image, preserving all the facial features of the man in the submitted photo (CRITICAL IDENTITY LOCK — preserve 100% of the face, hair, and expression). A hyper-realistic cinematic portrait of me, a muscular 40-year-old man with gray hair. He is performing a bicep curl with a heavy dumbbell, his veins and muscles clearly defined under dramatic side lighting. He is wearing a simple, tight black T-shirt that accentuates his physique. The background is gray and minimalist, giving full prominence to his intense facial expression and sculpted arms. The overall mood is powerful, bold, and typical of a professional gym photographer. Photographed with a high-definition portrait lens (85mm f/1.4), featuring sharp focus, deep shadows, and cinematic contrast.
