Ehh...
Wow... theres a lot you should do to make this animation better...
Well the Graphics weren't that great, the sound... well you should try any use your own voice... any your style isnt anything new...
The timing in this animation is dare i say it... terrible... the song seems to have slown down what you think is an apropriate frame speed or something... It took forever to get from the zoomed out shot of the HQ to the close in door shot... and like when the car was bouncing... way to slow...
Finally, you should touch up your backgrounds and buildings a bit, you could sure erase a bunch of overlapping lines that make the buildings look pretty sloppy...
Happy Holidays!
