A photorealistic full-body portrait of a 35-year-old European woman with medium brunette hair, captured while swimming in a river. Her skin is glistening with water, and her hair is soaked, dark, and clinging to her head and shoulders. She is wearing a black bra and black panties, both made of fabric that is visibly water-saturated, clinging to her skin, and appearing darker due to the wetness, with realistic water sheen and heavy texture. She has a cheerful expression on her face. The scene is set in a natural river environment with rippling water. The composition is a full-body shot, highlighting the interaction between the subject and the water. High-resolution photography, natural daylight, sharp focus on the subject, detailed wet skin texture, and realistic water droplets and reflections.
