The textural variety in this entry is for me the strongest thing about it. Nearly every song gives us multiple wildly differing tonal palettes, which is good, we're never bored as listeners. There are large sections of each piece dominated by a lead instrument with all its notes at identical velocity, which makes me feel a little bit like I'm trying to eat fifteen identical pancakes (?) so I would keep an eye on the dynamics of your lead instrument and maybe give us some more variation there. Overall I think it works as an accompaniment to a puzzler, so well done.
