A low-angle medium shot of a petite, chibi-style mermaid girl with a youthful appearance, floating dynamically in a colorful tropical ocean. The character has an innocent smile and gentle gaze, leaning forward with her arms wide open, blowing bubbles from her mouth. She features large, drooping red crystal eyes with strong highlights, red eyeliner, and long black eyelashes, paired with fin-like ears. Her exceptionally long, voluminous hair flows in a silver-to-pink gradient, with long side-locks extending from her bangs down to her chest. She wears a mother-of-pearl colored seashell bikini that reveals her midriff and navel, complemented by intricate gold chains and jewelry adorning her body, including a fine gold chain bracelet with a precise metallic texture. Her skin has a healthy matte finish, and her body is covered in pink metallic scales, ending in a magnificent, luxurious caudal fin. The surrounding underwater environment is filled with giant jellyfish and floating particles. The scene is characterized by intense backlighting, strong rim light, and the Tyndall effect, creating a mystical and ethereal atmosphere with lens flares, multiple reflections, and deep depth of field.
