Well I can see it.
I feel reluctant to comment on things I can't do myself, but here goes anyway:
-When he anticipates his jump, I'd speed it up a bit. The movements are great btw.
-When he "jumps" away from the pole and flies to the next roof (roughly between frame 60-80) he moves very fast. When an object goes up it gradually loses momentum until it reaches its high point, then it gains momentum again as it falls down. (as you know better than me: the bouncing ball kind of thing) Your guy doesn't really have that, he seems to move at the same speed.
-When he jumps on the boxes, I *think* the followthrough is too slow. I would expect him to go through his knees faster as it is quite a big leap he takes.
-Were you planning on adding in some pole movement? That'd be cool
I really like it btw.
