I'll start by saying: beautiful artwork, it immediately gives me the idea of a video game to find out about!
The story you wrote is very original, not banal and the music fits well. You did a good job also because you went deep with the plot making it a main topic even during the writing of the soundtrack, it's noticeable.
as for the music, a musical theme can easily be traced and it is interesting how it is structured in different ways and orchestrations in the songs: the intro is darker and more ambient, "The Tragedy of Life" has the same theme in the form of a waltz ( reminds me in some ways of the soundtrack of Succession). an extra point also for the specific description of the role of each song within the story.
I think you can still grow in terms of classical writing skills and also the creation of orchestral mockups (for example, I personally would have used less reverb in many songs, keeping them cleaner). Despite this, your work is noteworthy and does not lack originality!
