Side view walk hat doesn't look good, perhaps it should sway to the side instead of bobbing like that.
On the walk, his closer leg leaps back forward in a single frame. Thats fine, but his other leg doesn't do that, so he seems to have one spastic leg and another sedated one. Bring the speed to the other one, and he'll look like hes actually covering ground like the front view, not just ambling.
Keep it up.
