Cool, I really love the texture you put on it! I think he would look kind of neat if you have him in with maybe a brown or olive-green deteriorated kind of color, making him almost look like a "zombie."
Also, thanks for explaining to me about the nail thing...lol, sometimes I can get lazy when creating models and artworks too. :p I will occasionally do the part that I enjoy doing the most first, then do the most boring part last....or if I do not feel like fixing something I messed up on, I will just leave it and fix it later.
Also, the eyes idea was just a suggestion...I was thinking more along the lines of mechanical eyes though...but I understand why you don't want to add eyes. It probably would look too much like doll eyes anyway.... lol!! He still looks really awesome! Keep up the great work!
