Nice sig :) I got a few things that you could work on though. First of, the guys teeth look weird, they kinda look like Jaws from James Bond. Now if that was the style you were going for, they look great :P Second, I think you should do some more work on both of the weapons, both the bow and the spear? (non p2p) Could use alot more detail. And also the bushes in the background could use some work, it's late here and I'm tired but it looks to me that it's only one shade of green all the way, you should get into some detail there aswell. Other then that, the sig is very nice, the linework is really nice, and the shading is well done.
