Okay... yeah, racism's bad...
I'm not voting it down because I don't like the topic of racism, I'm voting it down because of the lack of artistic influence.
Sure the graphics were simple and animated well enough, but the overall flow of the film was pretty bad. It looks like the guy is sliding across the ground as he's walking. Also, the shadow on his front side for each step doesn't fit.
And probably the most overall thing was that it was short. All you really did was explore one aspect of racism, there are many different angles you could go off of. Don't limit your abilities there. If you're working on something, work on it hard and don't limit yourself.
