I really liked the intro, and I liked it again around 2:00. I also really liked the percussion for the most part.
The phased bass I think is cool but it feels a little too far off from the melody.
The synth that comes in around 3:40 (and other places) just ruins it for me - I get the effect that you're going for but it didn't really click in my opinion... That synth is almost the only thing that I dislike about this piece, but I REALLY dislike it.
Otherwise, I think you've made a pretty solid piece!
