Very good!
I am probably as not a big of this song as a lot of other people are. I guess I am lucky enough to not get that song stuck in my head all day like, well, some people. This was still great to watch because it simply had so much going on! You have showed us that you do not need to have the fanciest effects to have something really nice. I liked how everything was created with no black lines at all and just raw color.
It's great to see how funny the body movements are in this one. For every frame, there are crazy characters jumping and dancing around. It could use more of a background but it still works very well for itself. The song is so silly itself it would make sense something simple would be a good tribute to it. It's pretty much forgotten on this website now.
