Actually, not bad.
(First off, don't take the 8 badly, because I DO like this song.)
I like the ambient background feel that it has; I could listen to this while playing a puzzle game of some sort. My only thought is that, perhaps the percussion was slightly louder than it should have been in comparison to the synth and piano in the background.
I also noticed what you said about only doing remixes, and forgetting about original songs. I'd recommend against the idea, because you really get much more satisfaction when you crate something that is completely your own. Just because your scores might not reflect as highly upon your original work, don't give up on it! I do lots of video game remixes, too, and I DO enjoy it, but my favorite songs are the ones I make myself.
Anyway, good work here. I liked what I heard, and that's what counts. Nice job on the percussion, again. Very funky beat you've got here. =)
Peace and Respect,
