That's a tad too loud to be called "Ambient", pip. This is all over the place, no focus to be heard even though the sound itself is pretty nice, but the tempo and composition is way off, imo.

I'd suggest you try to create tunes with slower tempo; it fails to represent anything due to the fact it seems it always try to run away to the next verse.
Try to create an adagio, melancholic melody; that should give you a really good practice to commit to a single subject / theme / atmosphere. The bonus is that it should expend your abilities as an author.
