dude...
You honestly dont have a bad animation here. In fact, its all pretty good, but the thing is that you took a little too much time to extend the animation. I know you were trying to sync the music with the movie, but in those spots where nothing happened, you couldve added something. Like, for example. While Zero is falling in the very first scene, you couldve cut back to Bass and have him say something like, uh, "Oh comon. I know you have more than that." And then cut to zero (Still falling) have his eyes open, and block a bunch of energy blasts that fall towards him, recently fired from bass. I mean, I know thats just my opinion, and you have your own style, but really think about the logic of what theyre doing. I doubt that Bass wouldve just let zero fall to his death without at least looking over the edge and seeing what hes doing.
Overall, Its pretty good, just think about what the characters are thinking a litle more and you should have a good series.
