hmmmm...
I just watched this and I noticed some few things that you should fix on your next movie. When he falls down the movement should get quicker and quicker now it was like that it had lower gravity or something. And there's something weird when the guy pops, you should make him pop more and on the first frames move him more up and move him move smaller and smaller gaps then he falls down. This could be done with easing or just using onion skinning on two frames at the time. Hope that helps.
Other than that it's goood.
