A photorealistic full-body shot of a 29-year-old Asian woman with long black hair, swimming underwater in a lake. She is wearing a blue T-shirt and red sports shorts, both appearing soaking-wet, water-saturated, and clinging to her body with heavy wet folds and dark, unevenly soaked patches. Her skin and hair have a realistic water sheen and wet texture. She has a cheerful expression on her face. The camera captures her full body including the face. The scene is illuminated by natural light filtering through the lake water, creating a vibrant, clear, and immersive underwater environment.
