Restore this image, A powerful close-up, featuring a Chinese man around 20 years old, with subtle post-workout sweat on his face. He is wearing a white T-shirt. He has a neat buzz cut or short hair, with fine beads of sweat visible on his forehead and cheeks. His gaze is directed straight into the camera, conveying a determined and unyielding spirit, his lips possibly slightly upturned, revealing the satisfaction of challenging himself. The background is a blurred outdoor track or the edge of a basketball court, with bright and clear natural light, giving his face a healthy bronze glow, highly detailed, realistic, studio portrait.
