I' ve made this guy just for fun trying to focus on his expression, testing and learning some skin shading, texturing and fur on a human character.
The original head mesh is about 6k polys, here I' ve used a smoothed version (about 26k polys) just to avoid jegged edges.
The skin and clothes shaders are SSS and the hair/fur is made with Shave and A Haircut.
The rendering is made in a single pass and the hires version is 3636x2567 and took about 30 minutes to render it out.
No post work on the character just a simple straightforward rendering.

Thanks,
