Choir at the start was alright - although their were a few leaps in your soprano section which sounded unnatural. As Palestrina said - "Many steps, few leaps." And he was a master of choral music back in the day. Nice suspension around 2:13 - for a fact your soprano is playing a high C note but I'm trying to figure out what the strings are playing. Is it a Bb Major chord?
Sound wise, nice and thick sounds - very cinematic. Not thin at all. The Horn section is mixed very well, although my headphones are picking up a bit of Mid peak - just a bit. It may have been overall clipping though because of the nature of the climax of the piece. Please correct me if I'm wrong.
Strings as well - very well executed, and they play THAT motif which you would certainly find in cinematic pieces - that broken chord type arpeggio so I was very pleased to hear that kick in.
I'm not sure what else to say rather than good stuff mate!
