I wish you did more
This sounds like you just kinda redid the track with Fruity Loop instruments, adding nothing new to the song. Which is a kinda bland thing to do, in my opinion. Why should I listen to this song and not the original?
The main problem being there is nothing to really distinguish this as your own.
Now, I know that a lot of these types of songs go onto Newgrounds, and get praised (which is not exactly right either), but another knock against this piece is that its production is just a little bit lacking. There is nothing that quite new or inventive in the instrumentation, and quality of things leaves something to be desired. If this was a verbatim remake with awesome instrumentation, I would have scored you higher. But the whole thing has a 'demo' feel to it.
So the things that would have made this piece awesome would have been
A. your own spin on the theme
B. much better instrumentation
