A photorealistic full-body portrait of a 28-year-old Japanese woman with long black hair, wearing a blue T-shirt and silver panties, captured underwater in an indoor pool. The subject is soaking wet, with water-saturated fabric clinging to her body, dark soaked patches on the blue T-shirt, and glossy water sheen on her skin and hair. She has a cheerful expression. The scene is set in a clear indoor pool with ambient light refracting through the water. Full-body framing including the face, high-resolution photography, realistic wet textures, fluid water movement, and detailed skin rendering.
