I like it! Very simple, could use a bit more clarity in the mix as everything kinda mixes together, but for an ambient track, that isn't necessarily a bad thing. If you changed anything about this track, the only thing I'd suggest is mixing at least one synth, probably whatever your lead was in this, more clearly. By that, all I mean is making it less of an "ambient" sound, and having it come a bit into the foreground, but only slightly so that this can remain an ambient track.
Overall, great job!
