Prompt:

A slender teenage boy with slightly tanned skin stands against a pure black background, facing forward. His gaze is slightly downward, with messy short blond hair. He wears an open-front blue Hawaiian shirt with floral patterns, revealing his chest and abdomen contours; below, he has matching blue swim trunks tied with a white drawstring, decorated with white tropical leaf patterns. His feet are clad in blue athletic shoes. His posture is relaxed, arms hanging naturally at his sides, feet shoulder-width apart. There is a light source directly in front, creating fine highlights on his skin and the surface of the fabric. The style leans toward realistic or digital painting, with high resolution, and the background remains pure black to emphasize the figure.
