The music fully captures the protagonist's heartbreaking pain. The mix and composition of the tracks are good, but you could improve them by adding some details in the background and cleaning up the reverb and resonance a bit, in my opinion. Your strong point (which is the most important detail) is the underlying idea: you have it, and it works. Because of this, when I listen to the music, I can enter the world you want to describe. Experience will help you improve the technical aspects, but good ideas are either there or they're not, and you have very good ones in my humble opinion!
