If this is the best you can do, I would have to say...BLAMMAGE. But I'm assuming that you're going to get better. It looks like you spent more time drawing the characters than doing ANYTHING else, including things like animating and checking to see if it's smooth. I know everyone thinks it's the dumbest idea ever, but if you made an actual movie...like, as in a long one, with a plot, about Acid Rat, then it would be much more interesting. Nice choice of music.
