Very nice. The movements aren't stiff, choppy, or uncontrolled, and your easing is great. The only thing I can comment on is the foot placement when the stick is turning around; it looks like he's pivoting around on his heel. Pun not intended.
Those are some legs on that latest animation. XD You're animations are a bit stop and go. You need the flooooooooooooooow man. :)

I can see that your first animations were way too fast, and the new ones are kind of slow but they have very good movements, I liked the hits and kicks in the last one, them legs though, as Lordie said it's kind of stop and go-ish, maybe you need to ease a little bit your movements and work on the foot placement, it's pretty good bro, keep animating :P
