Realistic Studio Portrait of a Young Man

Create an ultra-realistic professional studio portrait of the same young man shown in the reference images. Preserve his facial identity and appearance with maximum accuracy: same face shape, forehead, eyebrows, eyes, nose, lips, cheeks, jawline, chin, ears, skin tone, hairline, hairstyle, moustache and light beard/stubble pattern. Keep his natural facial proportions and recognizable features unchanged. Show him facing directly toward the camera in a centered chest-up composition, with a calm, neutral expression and relaxed posture. He has neatly styled thick black hair with a natural side-swept texture, subtle moustache and short chin/jaw stubble. Dress him in a simple fitted dark charcoal-gray crew-neck T-shirt. Use a textured gray concrete/plaster studio wall as the background, with soft directional lighting that creates gentle facial definition and natural shadows.
