not bad
it's definitely different enough from the original, which is a very admirable. However, based on preferences, I still like the original better. Your animation is fresh, but what made the original so good was the character design (your characters just aren't anywhere near as memorable), and the visual gags were really funny and over the top back then. A minor thing also is that the lyrics in your version was too literal to what was happening on screen. I think it worked better if the animation wasn't so reliant on the lyrics... which i can understand is hard because the lyrics are extremely descriptive compared to the originals' more general lyrics.
