You asked for it...
So here's my critique.
The graphics could definitely use an overhaul, but graphics are never really the most important thing.
The thing about this animation is that what could have taken one minute took five. You should pay more attention to the flow of things, and make sure it's never to slow. Watch your flash animations as someone who's watching them for the first time and not as their creator. Would you blam this is it was submitted by someone else?
And also--credits were way too long.
That's about it. Keep up the good work, though.
