Overall I really liked that atmosphere you achieved through the different voice/string/synth textures. It was a very interesting blend of ambient/experimental electronic music with more orchestral parts. The only negative feedbacks I have would be: The March Towards had very cool basses, but I kinda lacked some melodic lead or sounds with higher frequencies to have a little break from the basses. The voice in The Blue Beauty On That Day sounded a bit weird to me, and too close. I feel like its volume was a bit too high, and that low pass filter made the voice sound too dry/muffled, which made the voice sound detached from the rest of the instruments. It was very good when there was a lot of high-end and when the voice had a lower volume, making it sound more distant (near 1:02). You could also try to add a high-pass filter on top of that low-pass filter to make it sound more radio-ish. It could work as well.
Nonetheless, it was a very interesting soundtrack. Very great job !
