It looks ok, but what's the story?
It looks like you have the right idea of getting a story together here, but there wasn't really any mention of it in this trailer. Oh, one thing for next time, compress the audio. I could tell within the first few seconds that the music file was what took up most of the file size in the upload. The graphics were ok as well. I'd just work on compressing audio and making all characters click in a better, more connective way. Good luck with your project.
