He's got character all right.
Fascinating model.
The subtle shapes of the skin in the face make him look very realistic.

I feel this is a very characterized model, yet the tissue under the jaw, the non-distinct-neck-muscles, cranial-shape and the placement of his spine/throat connecting the head to the torso, makes him very realisic in a way, that resembles real people, that has that special look on'em.

I also want to state that his jaw is probably a bit too protruding, for a "usual" person. But it gives him a strong character!

Two thumbs up!
