The fade of the darker fleshtone into the lighter face looks great. It looks like you use ink washes on parts of it, as it looks shiny.
When I want a matte finish but still want to do a wash, I add a little water to a darker shade of paint, and use that.
I like the stuff you did on his claws. I chickened out on doing that with the wolfen I just finished.

Good work. He looks great.
