3D caricature portrait with square face block AI Image Prompt

Create a high-quality 3D caricature portrait of a young adult man shown from the waist up, centered on a clean warm off-white studio background. Give him an oversized cartoon head and compact stylized body, with smooth glossy Pixar-like figurine materials, soft ambient lighting, subtle shadows, and polished clay-toy texture. The man has {argument name="hair color" default="dark brown"} thick sculpted hair, swept upward and back in dramatic layered waves with short faded sides, and visible rounded ears. His face is intentionally hidden by one large square privacy block centered over the entire face, filled with a smooth vertical skin-tone gradient from darker tan at the top to pale beige at the bottom, with sharp square edges. He wears a {argument name="shirt color" default="deep navy blue"} long-sleeve collared button-up shirt with visible seams, cuffs, collar, and two dark buttons; his arms are crossed confidently across his chest, hands visible with simplified rounded fingers. Use a front-facing slightly three-quarter pose, friendly promotional avatar composition, crisp details, rounded proportions, no text, no logo, no extra objects, and no background scenery.
