Some sculpting for thesis

I've been working on some personal projects and modeling/uving my mod kit for war for a little while, but I'm sort of getting the generic pieces over with so that I have a base to build on if I want to get more detailed/complex.. None of that is very exciting. But I just began sculpting the base for our corpse kit. I've been focused a little more on the face, and not so much on the body yet but I'm happy with how it's coming along. I think he needs to be quite a bit thinner. Any crits would be really helpful if anyone is even looking at these process books at this point. 

    

Here's my original concept and some ref from walking dead I've been using for the decay around the mouth area/sunken in eyes.
