Ooh, nice. Well, evil. Don't have anything to say about the model. Just learning Blender right now (and enjoying it) so for the moment I can only admire your poly-work and especially the UV map, but I can say something about the animation from intuition.
Judging from the bend of the elbows, it looks like it's supposed to be a walking animation, but it looks too forced. When I walk or see someone walk, generally the arms don't swing that much, and I hardly see any rotation of the chest either. If it's supposed to be running and I'm just seeing it in slo-mo, I think the elbows should be bent a lot more. The hips should also have more of a sin wave feel, rather than a sawtooth wave. I am from a region where people walk a bit more... lazily, so I may be biased. You have much more experience with modelling than I do though, and offer this only as my own observations.
The model's great though, hope my stuff turns out as well as yours.
