Focusing on the subpixel stuff I think it works pretty well on the torso, but not really in all the other places.
The animation on the legs and on his hands does not make much sense and does not look like movement at all, but just like changing pixels. On the crotch/belt area it pops too much in some frames. If you smooth that out I think that part should work good too. And the hair also makes no sense, it looks like it is alive more than anything.
