Great for what it is
As a test short this was great. I love the syle you are exploring, that kind of sin city-esque black and white style with strategically placed color. I'm impressed that you animated it FbF, rather than just tweening images like a lot of people do now days. However, this does have its downsides as your animation sometimes looked a bit choppy. The music was good, and if you made it into a full length movie or series, it would be great. THis has real potential.
