This is what came to my mind as I listened. Now granted, I've been reading a lot about the Holocaust in WWII lately so some images I get are directly drawn from it...
0:00: The beginning of this song is rather magical, but that cello coming in also gives an overtone of sadness. As we get further in, I could easily picture people walking on the street, sad at being oppressed.
1:10: The entrance of 'Glorious Leader'? Very stately and majestic.
1:59: Focus to the main characters, the ones filled with life, who want to do something about this tyranny? Again, you brought back that magical quality from the intro, but you made it more life-like. One of my favourite sections.
2:50: Raid on the streets, similar to WWII Europe, followed by an armed revolt?? At least that's what I'm getting.
3:44: I'm not sure what this reminded me of, but the progression after this section was real trailer-ending material.
4:48: A child (Rapunzel??) peeks out from the top of her prison, knowing what would await her should the guards come to open her door. Meanwhile, someone dies on the street, and the hero vows to put an end to the merciless killing.
6:25: You brought back the intro fragment, kudos. It started sad here, but then burst into so much of life and colour, like when Prince Charming leaps and bounds over enemies to save the woman he loves... and to let evil die, and good endure. This is the other of my favourite sections.
My thoughts are kinda hazy right now, but I can say this: you've blended life and death, evil and good, darkness and light with this piece -- and since this is what you were aiming for with the setting, congratulations on a job well done.
