A medium shot from a low-angle perspective depicts a young mermaid girl, appearing around elementary school age, swimming near the seabed in a mystical underwater world. She has a youthful face with an innocent smile, tilting her head slightly, with large, glowing red crystal eyes, long black eyelashes, and red eyeliner. Her silver hair is styled in an extremely long braided high ponytail with long side-locks reaching her chest, adorned with gold ornaments. She has fin-like ears with small gold piercings and a thin gold chain decoration on her forehead.
She wears a white cross-halterneck made of flowing water with intricate gold embroidery, tied at the sides, revealing her collarbones and midriff. Her attire includes gold side-armor on her hips and a front apron with white and gold embroidery. Her mermaid lower body and massive dual wings are covered in shimmering metallic red scales, complemented by golden wing-claws and a luxurious caudal fin. She wears long gold and metallic red bracelets on her wrists and gold jewelry with fine chains across her body. She holds a trident with a long white shaft, gold decorations, and a red crystal blade.
The scene is a crimson-tinted underwater realm with a giant, blurring crimson full moon visible through the water surface above. The atmosphere is mystical and dynamic, with strong wind-like currents creating a sense of movement. The lighting features intense backlighting, rim light, lens flares, and the Tyndall effect, with water droplets on her matte-finished skin creating a moist texture. The image has the tactile quality of a high-end PVC figure, featuring precise molding, reflections, and a shallow depth of field.
