레인보우 파스텔 3D 하품하는 고양이

A clean high-key 3D digital illustration of [a cat] isolated on a pure white background, posed in a dramatic stretching-and-yawning posture waking up. Low front-left camera angle with front paws extended forward toward the viewer, back arched upward, hindquarters raised, and tail curling into a high hook shape over the body. Smooth, clay-like, glossy-soft 3D surface with zero fur texture, coated in a vivid pastel rainbow gradient blending cyan, turquoise, pink, magenta, yellow, orange, lime, and violet across the body. The mouth is stretched extremely wide open, revealing a pink-purple interior, tongue, gums, small yellowish teeth, and prominent fangs; pink nose tilted upward. Rounded toy-like stylized anatomy, four visible paws with tiny extended claws, and an adorable yet exaggerated expression. Soft studio lighting with subtle ambient contact shadows under the paws, generous white negative space, centered composition. In the lower-right corner, a tiny handwritten signature and date reading "[July 29, 2026]" and "[Oyagi]". No background environment or borders.
