Hmm.
I know an inported midi when I hear one, especialy since none of your other tracks have nearly the same compositional or performance quality, which sort of kills the fact that there was any effort behind the piece at all. The point of remixing a track is you put the notes in yourself and make changes as you wish.
As for clarity, it was clipping out A LOT, especialy when the lead vocal instrument came in, and to be honest it wasnt really a remix. It was sort of a re-import with some shitty defualt instruments.
Either way, keep at it and try to make some stuff of your own, it still shows you're learning how to use your software...
