Grumpy Childhood 3D Character from a Reference Person

Create a super-cute, hyper-realistic 3D render of a toddler girl as a younger version of the person in the provided reference photo. Make the facial structure strongly match the reference image. Accurately reproduce the eye shape, eye color, skin tone, lip shape, nose structure, cheek fullness, eyebrow shape, and overall facial proportions. Ensure the toddler clearly resembles the same person at a younger age while retaining realistic childlike softness and rounded features. If an earring or similar accessory appears in the reference image, reproduce its size, color, and placement precisely. Expression: Make her distinctly grumpy and pouty. Rest her chin on her left palm, slightly squint one eye in mild annoyance, gently furrow her eyebrows, and push her lips forward in a stubborn pout. Keep the expression natural and believable rather than exaggerated. Hair: Adapt the reference hairstyle into a toddler-appropriate messy high bun, with soft, natural baby hairs framing the face. Outfit: Layer classic blue denim overalls with visible stitching and metal clasps over a white short-sleeve T-shirt. Pose and background: Seat her cross-legged against a clean white studio background, with her feet angled slightly toward the camera. Keep the composition balanced and show her full body. Style and quality: Use an ultra-detailed, Pixar/Disney-inspired 3D animation aesthetic, professional CGI rendering, a 1:1 aspect ratio, 8K resolution, sharp focus, cinematic studio lighting, soft subsurface scattering on the skin, smooth textures, realistic fabric physics, soft global illumination, and natural shadow falloff.
