Movement-wise, there isn't much that can be said. Everything's so cohesive and chains so well, and the timing is pretty much spot on. Any peice of criticism about your movements would honestly be just nitpicking and you might as well just ignore it. Whatever criticism can be made about your animation at this point would be the visuals. For instance, the way you've made the buildings look in there made them very distracting; the outlines are so thick and the black is so harsh. You can't easily focus on the character, this way. What I would do, if I were in your shoes, would be either spriting the whole buildings and turn the sprite's opacity down, or give the outlines themselves a higher value. What's important is to make sure that the background isn't as visible as the foreground and the character. Unless, of course, the character isn't what you want the viewer to subconsciously focus his view on.
There is also this thing with the building.stk
The least you can do is elongating those lines so that things don't look as wierd.
In any case, the animation is great, and what I said can be taken as a friendly comment which you might as well just ignore, if you'd like. I'm interested in seeing how is this going to turn out in the end.
