Wow, I didn't expect it to sound like that at all. So many things you've done here are super well done. The way the songs change and evolve from one mood to another is what separates your submission from everyone else's, and it's help by the fact everything has such good dynamics that transitions sound seamless.
One thing that stood out to me and I could be absolutely wrong, is that I heard electric guitars in track 4. I think how you used them (if you even did) was super masterful: they didn't stand out but they accentuated the violins and the brass and just gave them a more edgier tone, which is really how I think you should use electric guitars in orchestra.
I think a lot of consideration was put into overall loudness of each instrument and you knew how to blend everything together. This was an awesome submission.
