Not bad at all! You have very little to no wobbliness, and your foot movement for the most part is excellent.

I think though that you should incorporate the double-framing / easing concept, as well as a realistic gravitational feel. I can never emphasize this enough in animating: DOUBLE FRAME & EASE! Use it when action is slow or not speedy. If this applied with easing, where a movement doesn't just come to an immediate stop and rather to a gentle and slow stop, animating becomes ever more realistic.

Although the path the red stick was smooth when tossed in the air, it was slightly awkward. Try this: when he's hit up into the air, make a fast accent, try to really slow it down with double framing when he reaches the top, and then speed it back up again as he falls. With a little practice, you could probably get the hang of this in no time, and have air-borne objects look much more realistic.

So overall, your animation is really smooth, and follows a perfect path. But, if you try to incorperate easing, double framing, and a different feel for gravity, the anim would be even better and realistic. Sorry if my wording or advice is a little off, its 1:30AM where I am :p Keep it up!
