HAHAA! THE BOOBS!
Okay, props for trying to make the boobs look bouncy. Unfortunately, it doesn't really work all that well. Here's a tip: Boobs usually bounce because the body they're attached to is bounching. When she's running on the roof, the only things moving are her legs and her boobs. Her body has to move up and down if her boobs are going to bounce.

It will take you to an animation sample page that illustrates what I'm talking about. Watch the bear's head, and how it bounces differently than his body. If that bear's head was two boobs, it would be right on the money.
The other samples on that website are actually pretty cool for basic examples of animation techniques... anyone who's a beginning animator should check them out.
Also, the guy in your movie that got hit in the forehead with the sai... he didn't even blink! I know that if I got stabbed in the forehead with a sai, I would at least roll my eyes and hang my tongue out of my mouth before I died. But he just sort of bled and fell straight down, like he didn't mind being killed at all.
Anyway, for your second movie that was pretty cool. Keep animating!
