Great string and choir dissonance/consonance play. They feel like a solid unit moving along the track filling the dramatic general space and void in the piece. I really liked your usage of silences to achieve this. My only critique would be that the sustained choir feels intense but a bit piercing, because of its shrill timbre, maybe some eq/reverb to tame it a bit or make it morph at the end would improve the listening experience. You nailed the theme and I appreciate the touch of the bells tolling for the dead and the sense of storytelling.
