A dynamic medium shot from a low angle depicts a mermaid girl with a youthful face and an innocent smile, tilting her head slightly as she swims near the ocean floor in a crimson underwater world. She has long silver hair tied in a massive braided high ponytail reaching her chest, with long side-locks and golden ornaments. Her eyes are large, glowing red crystals with thick black lashes and red eyeliner. She wears a gold tiara, a thin gold chain on her forehead, and a cross halter-neck garment made of flowing water with intricate white and gold embroidery, tied at the sides and revealing her side-boobs, under-boobs, and navel. Metallic red shimmering scales cover her body, extending into giant metallic red wings with golden claws on her back and a luxurious caudal fin. She wears gold and metallic red bracelets on her wrists and golden side armor on her hips, with fine gold chains adorning her form. She grips a long white trident with gold decorations and a red crystal blade. The scene is filled with an ethereal, mysterious atmosphere, featuring strong backlighting, rim light, lens flares, and Tyndall effect, with water droplets clinging to her healthy, glowing skin. The image has the polished texture of a high-quality PVC figure with deep depth of field and complex reflections.
