I enjoyed this a lot. It's simple and soft enough to be background music, and it has a nice uplifting vibe. The main melody is super catchy.
This is me nitpicking, but I feel that the sweeps sound slightly too heavy for this kind of atmosphere. I would have reduced the low-end even further.
My main qualm with this track are the piano chords. It's kinda difficult to articulate precisely what I dislike, but I think this works: the chords add weight to the otherwise dreamy, reverby atmosphere. I would love to hear what you can do if you work towards making your piano arrangements more realistic and expressive (with the intent to do so).
