Realistic portrait of a 42-year-old African American man. Tall, broad-shouldered, strong jawline similar to his father. Short neat haircut. Intense, focused eyes. Wearing blue surgical scrubs with a stethoscope around his neck, standing in a hospital corridor. Professional and serious expression, but with a hint of vulnerability beneath the surface. Clean-shaven. Athletic build. Photorealistic style, cool hospital fluorescent lighting.
