This is a pretty relaxing track, I like it!
However, I've heard better, naturally. I'll try to mention some things I like, and the ones I don't :D

I like the calm mood, and the instruments. You've built quite an athmosphere using only an electric piano, a bass and a drum loop. To be honest though, I think you should've varied the percussion:ish sound more. You know the one that repeats over and over throughout the entire track (well, up until 3:18). While it sounded kinda cool at first, I think that it got a bit annoying after about a minute. But hey, I can't blame you; I'm even worse when it comes to percussion XD

I like the melodies and the chords as well. While this is pretty simplistic, I don't think this kind of ambient track needs much more to it. You've got a clear structure, and the mood is consistent.

I know I say this for a lot of tracks, and I wouldn't say it again if I didn't really mean it: Since this track lacks a real climax, and the structure is similar the whole way through, I think it would be pretty easy to loop. But it's not necessary. of course. The ending is just fine as it is :p

Anyhow, I enjoyed this track, and I checked out some of your other stuff as well!
It will be interesting to see what else you'll put on this site in the future ;)
Good job, and keep it up :'D
