You know what to do.
Obviously, the voices were to loud, or the music was too loud, one of the two. You can find a good free audio editing program on called "Audicity" on a download site. (search the Newgrounds BBS, they probablly have something about it) You can easily edit the volume in that program.
The animation wasn't bad, it was an interesting style that I think can be built upon, and from what I saw (becasue I couldn't understand them), it looked like it could of possibly been funny. Overall, it might have been decent if the audio was better.
Great music by the way. ;)
