A playful, high-quality 3D cartoon illustration of a human skeleton in a confident pose with hands on hips. The skeleton has a semi-transparent body showing detailed, child-friendly anatomy: a softly glowing pink brain inside the skull, a realistic red heart in the chest, visible lungs, stomach, and intestines in the abdomen, and blue and red blood vessels running throughout the body. The skeleton has large expressive eyes with eyelashes and a friendly, gentle smile (mouth closed or slightly open, no tongue visible). The face looks warm and approachable, not goofy. Style is glossy, soft, and slightly Pixar-like, with smooth lighting and subtle reflections on the transparent body. Background is a clean light green gradient with soft bokeh bubbles and a gentle glow. Bright, educational, kid-friendly aesthetic. Vertical composition (9:16), full body centered, high resolution, sharp details. Ver mais
