How do I submit an updated version of this image?
Nevermind. 
The shape is really well done, but the shading is lackluster.
Lazy shading. It really could be real pownage with shades, light sources, details, etc. Nice though. His right arm looks odd.
I think this has Hall of fame potential can't wait to see waht more you add.
really nice :). i just feel the head is a bit to much left (to his right shoulder).
