I was drawn in to this composition the moment I started listening to it. I think it really captures the sense of warmth and brightness of the outdoors as evoked in the artwork, and the timbrel palette complements the pixel art palette well. Those lead bells grab my attention, and I enjoy listening to hear how the other layers move in relation to it, particularly the bass. It always feels like the lead and bass are always moving in the same instance, but not at the same time, so there's this strange sense of lagging, even if some notes do line up. Part of me wanted the bass to have more prominence on its own, especially in the moments where the bells were not playing, but I think this also allowed for the warmth of those other pads to break through.
While I love the overall "vibing" sense of the composition, I found a lot of opportunities for developing the sections to be truncated. Very early on, at around the 0:40 mark, the same idea is heard, but at a different key. It seems as though the next iteration after that is also gradually descending in terms of the key that it's in. Having strayed farther from the original key the piece started in, it did seem jarring to jump straight back into it and I felt that it, melodically, broke the sense of smoothness given off by the rest of the composition.
It's interesting because at 1:25, the composition diverges again, and I think the development here is a lot more sound than the first diversion and allowed the transition to the repeat section to be more organic.
In a sense, I do think the 0:40 change could have something added - an additional chord in the progression, maybe. Even an extra layer to the texture could be interesting - something syncopated in the lower-mid end to counterpoint the bass? It all depends on your personal taste, and I'm just spitballing suggestions. I like the idea of having a slight diversion before going into a longer diversion at 1:25; I just wish it were done in a way that would not make the immediate repeat at 0:56 have this unsatisfying sense of "oh, it's just this same section again".
Your ideas here truly bring out brightness and relaxation and just the mood in itself is something I could listen to for quite a while. In these stressful times, I appreciate pieces like these. Great entry.
