Hmm, the animation looks fairly smooth. However, the walk cycle isn't reading too well. Unless every character that uses this template is an old style war veteran, I'd suggest taking a look at the animation one more time. It looks as if he is marching/stomping intead of walking. The dramatic rotating arms, and robotic stiffness of the head also add to this strange motion. I think the reason for the marching illusion may be due to the fact that when he raises his legs, the area beneath the knees(shins and so forth) stay darkened, while light shines of his knees. If he was walking normally, wouldn't those portions of the leg light up? Again, if this was intended, then it's fine. However, if it is indeed a normal walk cycle, it's not exactly fitting...
Still, these are looking great. Are you making attack animations also, or just the test walk cycles?
