Mad world -short- Good Start
It looks like you've been practicing with walk cycles. They were the strongest thing this animation had going for it.
Overall, you made a pretty literal translation of a song and used a style that I don't think fits. Don't be discouraged though, your animation was better than a lot of the crap on here. Try putting more detail in next time. Several objects were static and moved together... which is fine, but if things aren't going to move, they can stand to be more detailed. You're heading in the right direction -- keep with it!
