This is mostly like orc from Lotr movie (that's why he looks a little differ from orcs you can see in some games/movies/etc).
I used Vray for render and result was far from what I want to get. So I create another render (only head) using MR and its SSS fast skin shader and composite it with entier scene in PS. After PS-correction I load result in AE and apply DFT Digital Film Lab with some settings. After all this routine - here is the result. Can't say I'm very happy about what I get, but I have tired of this scene.
C&C are welcome.
