Stylized 3D bust portrait of a cute girl with rainbow hair and pastel eyes, featuring soft highlights and a smooth, clay-like finish

Prompt

Create a clean 3D stylized bust portrait of a cute young girl with soft toy-like clay material, centered on a white background. The character has a large rounded head, small delicate nose, gentle closed-mouth smile, smooth cheeks, and large simplified almond-shaped eyes with no visible pupils, glowing with a pastel gradient. Give her long thick wavy hair with a sweeping side part and sculpted ribbon-like curls framing the face; the hair falls behind her shoulders in broad soft waves. She wears a simple sleeveless top with a rounded neckline and rounded shoulders, shown from upper torso upward as a bust sculpture. Use an iridescent rainbow pastel color palette blending cyan, turquoise, violet, lavender, pink, peach, orange, mint, and soft yellow across the entire figure, with smooth gradients and subsurface-scattering softness. Lighting should be bright, diffused, and studio-clean, creating a glossy matte-plastic/clay look with gentle highlights and minimal shadows. Composition is vertical portrait, three-quarter view facing slightly right, head and shoulders filling most of the frame, lots of clean white negative space around the figure. Add a small handwritten artist signature and date in the bottom-right corner reading July 29, 2026 Oyagi. Keep the image text-free except for that signature, with no background objects, no hard outlines, no photorealistic skin texture, and no extra accessories.
