A dynamic medium shot from a low angle depicts a young mermaid girl with a childlike face, styled as a highly detailed PVC figure in a vignette setting. She has long silver hair tied in a braided high ponytail, with long side-locks reaching her chest, adorned with gold ornaments. Her eyes are large, glowing red crystals with thick black lashes and red eyeliner, gazing gently with a shy expression as she tilts her head. She wears a cross-halterneck top made of flowing water with intricate white and gold embroidery, tied at the sides, revealing her collarbones and navel. A front apron with similar embroidery hangs from her waist. She features finned ears, small gold earrings, a thin gold chain on her forehead, and gold side armor at her hips. Massive metallic red wings with golden claws sprout from her back, matching the shimmering metallic red scales on her body and her luxurious tail fin. She holds a long white trident with gold decorations and a red crystal blade. She is positioned at the boundary of a mirror-like water surface, with a giant crimson full moon reflecting above. The scene is bathed in intense backlight and rim lighting, creating a mystical atmosphere with Tyndall effects, lens flares, and shimmering water droplets on her matte-finished skin. The color palette is dominated by deep crimson and brilliant gold.
