Pretty cool Don, I like the character overall and the stuff on his back is really cool, I think you should emphasize that a lot more with the color. The pose on the foward facing guy looks a little squashed, i think it may be that his abdomen is a little too think, i think bringing it in a bit would make it look more natural and help with that leaning back posegood work though, keep it up
Well. It seems my comment never registered on here. Digging the design a lot. Definitely has that flare your work has. But make sure you are drawing distinctions between the armor and the actual guy.
