The animation is actually decent here, but I'd recommend you get a better animation program like Flash 8. It'd help smooth the outlines so it doesn't look so rushed. Speaking of which, you should have mouth movements here. It doesn't have to be perfectly lip synced, the mouths just need to move up and down. And lastly you should make legit backgrounds. It doesn't have to be amazing either, but it'd be better than having single colored backgrounds. You got some talent here, it just needs to be improved on. Good luck!
