To be honest, before you make anymore animations you have to get a better program. One that is quite good and I think is for free is "Audacity." If you get that program your animations will be alot better.
Also there was nothing flash about this animation. You need to create a better script as well. All this one was about was a horse saying it needed a crap and that was pretty much it.
I am not trying to be mean about all this, but if you follow this you will see an improvement.
Another thing is that it needs more movement. The whole way through was just lips movement. Make an episode where they run around the place or something.
Anyway, it is quite good for a first timer. Hope you do well
