Witherbark Battle - One

Source: World of Warcraft
Characters: Undead Male

Another commision for a World of Warcraft friend. This is one of three characters that will be featured in a full battle scene, locked in combat with Witherbark trolls. I plan to draw each character seperately, then pull them together in one scene using Corel Painter IX. After that, I'm going to fill in the Witherbark trolls and the background...I hope it works out *crosses fingers*. I'm almost afraid to color this.

Any tips on anatomy and other things in general would be greatly appreciated!
