Some really cool ideas here and I think you captured each emotion incredibly well for each song, and pretty impressive considering the amount of time you had! Just a few quick notes:
- Someone already mentioned it, but dont worry too much about runtime, short and sweet is fine! Your main themes for each song was lovely, and i think by limiting it to maybe two repetitions tops for a format like this it will help make sure the listener does not get bored, but admittedly this is a nitpick.
- This may be a stylistic choice, but i noticed especially in the first few songs that a few notes kind of started to slip off the beat occasionally, i understand this may have been a product of time and that sometimes random things like timings can easily slip through, so dont worry about it too much!
Overall i did really enjoy listening to this, your instrumentation was lovely and again i really liked all the ideas you had and how well the corelated to your story. Well done!
