I gave it a three, because the notes were alright. But with dance pieces, especially Sonic remixes, you want to stand out. And this piece just didn't.
The dynamics need work, especially. The entire piece is almost at the same dynamic range, it feels monotonous. A good dance remix would wind things down at some point, build up the tension, and then come back in full force -- I trust you'll understand what I mean when you hear good dance pieces.
Then, samples. They were good. But I tend to be very, very iffy about the transition between the intro and the main theme. First, soft 8-bit samples, then a loud synth? Something doesn't click here. In the original Genesis version one was only slightly softer than the other -- it was noticeable, but it wasn't a drastic change.
Also, try a little bit of variation. I've noticed that the bass line is similar to the Genesis version -- pretty much everything is, except for the drums and samples. Adding variation will give this piece your own personal touch, and that's what listeners are here for.
