character: wakasagihime, A (masterpiece, best quality, 8k, ultra detailed:1.3) medium shot from a centered-lower angle captures Wakasagihime, a mermaid who is half-human and half-fish, floating serenely in a deep clear lake. She has light blue long curly hair adorned with pearl hair ornaments and lake blue half-closed eyes, her expression gentle and serene against pale translucent skin; she floats with her arms relaxed at her sides, her hair flowing naturally with the water current. She wears a light aqua kimono made of sheer gauze fabric that drifts weightlessly in the water, transitioning into a gradient cyan-blue fish tail with pearlescent scales and translucent fins. The underwater environment features dappled sunbeams filtering from the surface through a Tyndall effect, with floating plankton particles, soft algae, and pebbles on the lake bottom, while countless transparent air bubbles rise slowly around her. Diffused underwater lighting creates soft rim lights and caustic light refractions on her skin and tail, utilizing a cool cyan-blue color palette with cinematic depth of field and a quiet, melancholic atmosphere with ample negative space.
