Well...

It does seem like you spent a lot of time doing this. For the plus side, the mouth movement to the speech sounds were actually very well done, at least in the first part with the two figures. In the second part, what I'd recommend doing is watching your own mouth in the mirror saying those exact words. There are quite a few parts where it didn't match up very well with the single big character because you used the shot where you could see their tongue.

There's a whole lot to be improved on. The background didn't fit with the characters what so ever and the joke (if it was meant to be a joke) at the end wasn't funny at all.

I'd suggest making the design of your characters more interesting and have more of a dialogue than a monologue. I think it would be good for you to keep trying, but unfortunately, this one isn't quite there yet.

Animation aside

even though the animation was bad, that's alright since this was suppose to be a joke clip anyway. However, since the joke isn't really funny (at all), I'd say this fails on all accounts. I don't mean to sound like a dick, I'm only saying that you should either improve your humor or your animation, but this just isn't entertaining. Judging by the way the actor sounds, I'd say you're probably still a kid, so you've got plenty of time to improve. Good luck
