On your newest: terrible foot placement, the kicks are much too slow, there's a lot of shakiness in the head and you shouldn't really be using effects until you're better at pivot, using effects like you have is just like using short-cuts in animating. It doesn't help us or you at all. Good to see you have some knowledge of smoothness, though. But you have to remember, if you over-ease everything and make everything too smooth, you'll lack realism.
