Keep the exact same 3D animated toddler character design, facial features, proportions, cute happy expression, big blue eyes, clothing (light blue long sleeve shirt, brown overalls/dungarees, brown shoes), and soft studio lighting on neutral background, but change the hair color from blonde to soft natural light chestnut brown hair (светло-каштановые волосы). Maintain identical Pixar/3D cartoon animation style, high quality 3D render.
