So I'm not used to drawing unrealistic things, especially robotic canines. So can you imagine how excited I am right now about how this sexy thang turned out?  
My first drawing of Volk, my Psi-borg bull terrier mutt. I'm so goddamn proud of the shading and his robotic parts I could cry. Yes, he's hovering in the mouth of a cave. His cave. Being all threatening and mean. :3 Just the way I like him.
