Nice use of color and it is very long. The animation is choppy, and it should be much smoother. Adding more detail and style to your characters would help them stand out.

Could do with a lot of work. There isn't really an art style, because every shot looks inconsistent, especially with the linework, which doesn't connect most of the time. You also don't really do anything interesting with the visuals; Obviously when re-creating something as your own you can bring something new to the table but you don't really do that, it's just stickmen standing there with their mouths open. Try adding more relevant imagery to fit the lyrics.

Try developing your style more and practice making the art a lot more cleaner. And it's pretty much a given but practice animation more, so there's more cool stuff to look at.
