A medium shot from a side angle depicts a mature woman floating in a dynamic, weightless pose deep underwater during the night. The woman has long, flowing hair with a white-to-black gradient and a gentle, serene smile on her face; she is dressed in traditional Chinese clothes featuring a white and black color scheme that billows softly around her. She is surrounded by white butterfly koi fish that swim gracefully through the dark water. Beams of ethereal moonlight pierce the surface, casting luminous moon rays that illuminate the scene. The visual style is an impasto-influenced anime painting, characterized by pronounced lighting highlights that contrast with rich, muted tones to create a dramatic, emotional surface, blending a subtle retro flair with Western illustration techniques.
