I know, I know. Fuck this guy, right? Haha, but seriously, he was an amazingly well done character. I gotta give Naughty Dog that one.
I actually used the likeness of Ray McKinnon (Deadwood, Sons of Anarchy) for this one: http://img832.imageshack.us/img832/7528/7stl.jpg I just thought he has a rather interesting face and could work pretty well for this character.
About 20 hours!
Airbrush + Texture brushes.
Dodge/Burn and Sharpen/Blur for finishing touches!
Reffed off a few in-game screenshots to get his face looking as true to him as I can while still keeping a more realistic look at the same time. Tricky but fun stuff!
