Warcraft? No, I believe this is a WHFB Orc, specifically the 6th edition army book's cover Boy (or Nob). Same tooth decoration (hard to see on Lexicanum, but my local Battle Bunker has a five foot mural), and a boquet of mushrooms, which Games Workshop greenskins are big on because they are part fungus in both WHFB and WH40k.
