A cute little girl is running in the style of Disney, as a full body cartoon character on a black background, wearing sportswear and sports shoes, smiling with brown hair tied into pigtails. She has an animated face in the style of Pixar, with her eyes wide open and mouth slightly closed to show the happy expression of cheerful laughter. The scene captures her dynamic movement as she runs at high speed. Cartoon character design, 3D rendering, with high resolution and high details.
