The chiptune works so well with conveying both the spacey atmosphere while creating a sense of comfort. It's an entry I really enjoy listening to, laying back and being immersed in the journey, and I think it nails the concept of the artwork and its style on the head.
The various sections of this piece are fantastic and I love the ideas that are explored in each of them. I do get the sense of a certain progression in the musical narrative, and I think the order in which the sections follow each other makes sense.
What I would have loved to hear more of, however, are the ways in which these sections connect with one another. For me, the biggest issue I have with this piece is that it feels too "sectional". Often times, the end of a section and the start of a new one would come across as forced. One example I can think of is at the start, where the piece seems to be building momentum off the repeating melody, and that momentum just suddenly stops when the chiptune is abruptly cut off at 0:41 and replaced with the strings. Maybe it makes sense in the Author Comments, but I think when listening to the piece on its own, that's one instance that takes me out of the track's overarching mood and narrative.
2:07 is the other transition that comes across as abrupt, though this one at least has that sweep that allows it to work a bit better (though the differences in the two volumes feel a bit too drastic). It doesn't help that the way these two examples transition are very similar to each other, and I believe that this is part of what makes them feel like transitions made solely out of obligation. It just feels like a stark contrast to the composition in the sections themselves, which flow more naturally.
My favourite section was the one starting at 0:48 with the syncopated chords and the alternating square notes. It was such a great buildup, especially with the way those chords get filtered in and the variation on the main melody tying it all together. I am curious if the "whoop" vocal sound effects are also supposed to represent the "purity of space" like the acoustic drums and strings are. To me, those sounds also seemed out of place with the rest of the sound design, but they don't appear super often and didn't bother me as much.
Overall, this piece has terrific composition, and that and the chiptune mixed with the strings helped to connect it more with the artwork inspiration. With more organic transitions and development through each of its wonderful sections, it would be a comforting musical masterpiece.
