Looks awesome
This looks really great, but the audio could use a little work.
First off, it would sound much better with different voice actors - at the moment, it sounds like one guy is doing all the voices, you need a little more diversity to make it easier to know which character is talking when. Easily recognisable voices really strengthen an audience's grip on character development.
Secondly, I would swap the music for something a bit more moody and downbeat.
Having said that the artwork and animation are both great, so you have a winner here.
