The Sea, the Moon, the Stars: I was trying to figure out which instrument represented which character: I think the piano is the sea underlying the moon (cello) and stars (violin) as they dance overhead in the sky together. Was that what was intended? I really like the B section you wrote- it pairs veery nicely with your main theme.
The Fishing Village: The viola (violin?) is produced very well and sounds great as a solo! This fun melody conveys the joyful nature of the village while also allowing space (exemplified between the piano left hand) that may represent the happy waiting that makes up a bulk of the activity of fishing. This is a short theme, but I think it’s very well-written!
The Island in the Fog: The quiet strings are quite ominous over the sustained piano. The comparison and transition from the previous track to this one is my favorite part of your soundtrack because of the stark shift in emotion and the clear musical description of the story.
The Gathering Storm: It’s impressive how you are able to create quite a large sound with only 4 instruments. I think you weave them all together very well to create the feel of a storm that feels destructive, but also carries a feeling of melancholy possibly for the despair that follows in its wake. It would have been nice to hear some sort of resolution, but I really like what you have completed here! Great work overall and thank you for sharing!
