Pixar-Style Freckled Girl Avatar

Create a Pixar-style 3D animated half-body head based on a reference image, depicting a cheerful and lively person with messy blonde hair in a high bun and freckles. She has a bright smile, bright eyes, and wears a green corduroy shirt jacket and a white T-shirt. The background is a seamless white, and the rendering effect showcases flawless skin and soft, cinematic studio lighting.
