This was originally just a doodle for my sketchbook, but after I did the particle hair, I really thought I got it. This is the first portrait I’ve done that I’m actually happy with, especially the eyes…
Very nice! I agree, the eyes are great. 
Great caricature!
Are you going to advance the materials and lights some more? Would love to see this with more true-to-life skin, etc.
I probably am going to do some more work on it. I need to get some practice with cycles, so I’ll use him as a guinea pig.
I like the style of this render, though. The materials are as-is straight from Sculptris. (The sculpting was done in Blender and sculptris, and the texture was painted in sculptris.)
I’ll retopo tonight, and bake the maps, then start messing with cycles. Can’t wait to see what he looks like with Subsurface scattering!
Here’s a quick update (This is Blender Render engine):
