I agree with samulis, the lower registers on the orchestra don't match well with the low voice of the men chanting. I agree that spreading out a variety of octaves with french horns would make it sound much better.
I know how tough writing music can be, and as a fellow musician I think that this is a very nice piece. I really like the incorporation of the multiple ranges of voice chanting made this piece sound really nice. I think you did a very good job with the whole remembrance theme. 4/5 8/10
Keep up the good work :)
