This isn't a bad start...
but I blammed it because I don't really see why it would belong on Newgrounds. The way the mouths synched up the background music was done well, and the quality of the audio was nice. It's just... too simple. I understand this is something you did so you can learn flash, and thats wonderful, keep it up. But I just don't understand why this is rated so high to the point it is going to end up taking up space on the NG servers. Not bad, I just don't think it belongs here.
