Adorable fille chibi avec ballon en forme de dragon sur fond bleu

A cute 3D illustration in the style of a toy character with exaggerated proportions: a little girl named Rhaenyra with a large round head, a tiny body, and enormous eyes, dressed in a miniature silver-gray Targaryen dress, her light platinum hair pulled back into a small ponytail. In her hand, she holds a string, at the end of which floats a round, plump dragon. Like a balloon—a spherical body, tiny wings, small horns, a contented face with closed, arched eyes—the dragon is a creamy white color with a golden sheen. The string hangs slightly between them. A bright, solid background of deep sapphire blue with a soft vignette, pastel accent colors. Soft, diffuse lighting, rounded shapes without sharp corners, plush surface textures, minimalist editorial style, Pixar-like 3D render, cute chibi proportions, centered composition, full body visibility, lots of negative space, cozy and whimsical mood, high detail, 8K render -- 9:16
