That's some soothing tune you got there. Quite relaxing. I pretty much like it.
A lot of the drums are really clean in the mix but I seem to hear a soft kick with delay effect in the background around 3:45 - 4:30, right? I don't think it's a nice addition to the drums. I don't like it, it sounds like something random is ticking.
Also, I think that you would need more bass for the small sidechain you have in here.
The synths are truly amazing in this one. I like how chill they sound.
Good work dude. Keep on working with these tunes! (:
