Decent at best:
First of all, I have to say I'm sick of people saying that "this is their first animation ever, just got Macromedia Flash yesterday" bullshit. Now that thats through, I think that your animation was decent. Why? It wasn't productive, the voice acting wasn't great (the levels were slightly off and there was some microphone interference at points, like you hit the mic with your chin) and overall, it was boring. However, the animations were good (It does not look like you drew them yourself, but they were good none-the-less. And the idea was sort of funny. If you keep doing this, I think you'll make some pretty good stuff.
Final Note: In my opinion, the best part were the credits. The music and text were awesome. Seriously.
