Yea, not good.

The voices were good, but however, the animation, wasn't. I liked the black and white thingy, but the tweens weren't and the mouths don't move very well. The Explosion sound was epic to. I guess it gets a 5.

Absolutely not...

This has nothing to do with any class besides maybe a class for flash animation, or just animation itself.
If this were the case, Please add some color and differentiation between characters. (Faces look wayyy to similar, only difference is the hat)

Also, get a fucking better mic if you're going to do any production at all. A 10$ Logitech mic available at any Wal-mart is 1000 times better then whatever you used here.

Also, next time, at least go to http://voiceacting.proboards.com and get some quality voice actors.
I don't know, you may be a good voice actor, I just can't really hear you and all.

And, get some background music man. There's alot of free ones that sound amazing at http://incompetech.com/m/c/royalty-fr ee/

Anyway, Continue making flashes. You most definitely have the potential. Just needs alot more elements to make a great one :]
