I like the dreamy sound design at the beginning. The chord progression is a bit cliche, and at :15 the piano and bell-like synth lines kinda trip over each other a bit. I like the crisp drums at :29 and the cutesy breakdown at :44, although the transition into :44 was a bit abrupt. The mix could be a tad sharper here, especially in some of the mid-range harmonies. Some more compression all around would probably be advisable, and during some of the more minimalistic sections (like 1:30), some more reverb might help fill out the atmosphere. During the busier sections (like at 2:13), some of the instruments are hard to hear, especially the string melodies. It might help to look into panning effects as a way of making all the harmonies sound more distinct.
That said, I like the emotional quality of the section at 1:44, as well as the added string harmonies at 2:00. Clearly, you have a good sense of harmony, rhythm, and instrumentation. The arrangement sounds a tad formulaic here - there are regular changes to the texture every 8 bars or so, but not a lot of ebb and flow within those 8 bars. Overall, the composition is strong here, though.
Overall, I love the tranquil mood and melodies in this piece. Crafting a “looser,” more dynamic arrangement and tightening up the production quality would help take it to the next level, but as it is it’s both catchy and relaxing. :) Keep at it, Qwerzer! ^_^
