Photorealistic portrait of a young man. Wearing a red and white patterned short-sleeve button-up shirt, unbuttoned, with matching shorts. Standing outdoors with one arm relaxed along the body, looking straight at the camera with a neutral expression. The environment is tropical with tall palm trees and clear blue sky in the background. Lighting is bright natural sunlight, creating clear shadows. Camera angle is a medium full-body shot from slightly below eye level. No makeup, natural face. Skin texture should look natural and realistic, hands must be anatomically correct.
