Its mixed down to a very low volume. This is an energetic song, you should consider raising the master volume. I have the volume all the way up on my headphones right now, and im having trouble hearing some parts. Also the timpani and other drums have way too much mid and low end. I would eq the loud junk frequencies out of them. Other than that it was pretty good. I've never personally heard the original, but your composition definitely sounds like it did it justice.
