3d chibi businessman

Refine this 3D chibi male model to be HD and extremely clean. 1. Remove Smudges: Completely erase all dark, dirty color patches on the back of the head, neck, and skin. Skin must be flawlessly smooth and even-toned. 2. Crisp Geometry: Sharpen the edges of the black suit lapels, white shirt collar, and tie. They must be razor-sharp, not blurry or melting. 3. Solid Colors: Fix color bleeding. Boundaries between the black suit, white shirt, skin, and hair must be perfectly sharp with distinct, solid colors. 4. Details: Improve hair topology to show distinct locks, not just blocky chunks. Make the overall texture highly polished, sharp, and clean like a professional render.
