A medium shot, eye-level anime illustration depicting a young fish girl exploring the deep ocean, positioned centrally as she swims through a vibrant coral reef. The girl has shimmering iridescent scales along her skin, flowing translucent fins extending from her back and forearms, and wide, curious eyes reflecting the light. She is dressed in a lightweight, organic garment made of shimmering sea-silk that drifts in the current, her hands gently reaching out to touch a floating, glowing jellyfish. The surrounding environment is a lush underwater wonderland filled with towering neon-colored corals, swirling schools of tiny silver fish, and ancient shipwrecks partially buried in sparkling white sand. The atmosphere is magical and serene, characterized by caustic sunlight filtering through the water's surface in dancing beams, a deep turquoise and ultramarine color palette, floating marine snow particles, and a soft depth of field that emphasizes the girl's sense of wonder.
