Morning Light: I'm very delighted by this light-hearted melody, and the light variations of it as the piece goes on! Each new phrase is pleasantly different from the last, with enough transitional material and a contrasting b-section to drum up interest. You've done very well here. My only advice is that some instruments sound a little out of place-- the bell, and the whipping percussion sound, for instance-- and that the mixing is very guitar-heavy, with some instruments drowning out others. Mixing is tough, though... and not everybody has extensive instrumental libraries. So from a purely compositional perspective, I'm very impressed!
Under the Umbrella: another beautiful and well-written melody. The tone switch from gentle piano to whimsical orchestra was also very nice! All the textures you explore are very beautiful, and pleasantly contrasting-- I might even invite you to be more restrictive, as lots of textures and instrumentations don't get revisited after their initial presentation.
On the Pier Under the Stars: for two seconds there, I was like... 'Spirited Away?' this is a similar melody for sure, but I have no grievances. This track is probably my favorite: another delightful melody, with a good balance of variety and familiarity.
In all, I'm proud of your work here! Between the story, cover art, and music, you've created something cohesive and very enjoyable to listen to. Great work, and keep writing!
