It was Ok...but not that good
First, just to clarify, I love that song :)
Anyway..
What it appeared to me was you were all ironically trying to be trendy, that animation style has been used over, and over, and over. The simple FBF, not very detailed characters, small eyes, big mouths, the occasional tween, and only a very small selection of people can pull it off. Unfortunetly, I didn't see anyone do it exceptionally well in here. And some of the parts were just plain lazy, lacking in depth.. (E.g, the part that had the world spinning for about 4 seconds)
Anyway, my advice to all of you would be to go back, and improve your skills. The majority of you obviously have some talent, but you're not very outgoing, which is the main problem. Try somthing new, try developing your own style, dont be afraid to add details that you dont think would matter.
Just remember, there's allways a Ctrl+Z
