Needs work
You shouldn't have had those tiny stick figures for characters, and should have made the whole movie like you did the second half. The animation itself is well done, but the graphics need a lot of work. The backgrounds need work, rather than obvious line tool lines. Flesh out the graphics of your characters, you need more than just a grey and white character. You know, costuming and stuff. I would have liked some other sounds, like sound effects and/or dialogue, other than just the "Smack My Bitch Up" song playing. Lastly, it was a fairly decently animated movie, but try and get away from the blatently obvious Dragon Ball Z style.
Work on these things, and I believe you will have a quality movie.
