Smiling Male 3D Caricature Portrait

Create a highly detailed 3D caricature of a cheerful man with an oversized head and exaggerated cartoon-style proportions while maintaining a semi-realistic finish. The head should be significantly larger in proportion, with a noticeably smaller and compact body (strong caricature ratio, around 1:3 or 1:4 head-to-body proportion). The character has a big, expressive smile showcasing large teeth and full of personality. Hair should be natural length, voluminous and stylized (e.g., curly or textured), adding to the playful look.
Outfit: A short-sleeved white button-up shirt, brown high-waisted pants with a black belt, and simple traditional sandals.
Pose: Casual and friendly — standing upright (slight body tilt) with one hand gently touching the chin in a thoughtful yet approachable manner. Body language should feel natural, relaxed, and full of charm.
Style & Rendering: High-quality 3D render with smooth lighting, soft shadows, and clean materials. The style should balance realism and caricature exaggeration (similar to modern animated film characters).
Background: Clean, pure white studio background with no distractions.
Composition: Full-body, centered framing, vertical aspect ratio (4:5).
