seaside - Some highlights in this track for me were the string notes at 0:50 and the piano chord at 1:09. The piano could have a more delicate quality to it (slower and softer dynamics).
wildchild - Interesting genre switch that is quite fitting for a rocker character archetype.
hermit - Cool use of retro sounds and nice job with reusing motifs.
flying tomatoes - Nice switch to a jazz style. I would make the saxophone louder in the second half.
distant waves - Great closing piece that calls back to the first track.
Good job here! Be careful with dissonance—I would use it more sparingly, contrasted against moments of consonance. Similarly, tracks 2, 3, and 4 would benefit greatly from B sections that contrast your existing ideas, like a change in texture or chord progression, for example. Overall, I think that it is really cool that you were able to work with so many different genres for this soundtrack and use the different genres for character themes—maybe that idea could even be extended towards entire chapters or different interactions for each character!
