@Demi - I'm hesitant to push the flesh any higher, since I don't want to lighten the overall tone. I suppose I could darken the shadows a little more. As for the nails, I'll probably do similarly. I like the orange-brown tone. A natural bone color would change it significantly.
Unfortunately it was not without incident. While I was trying to wiggle the pin out of his foot, his ankle flexed and some of the paint flaked off. Also, being a zombie, his outstretched arm fell off while I was wrestling with his leg. Both issues have been corrected, and with a little touch up paint it won't be noticeable.
