Magnificent. This sounds incredible. It emanates the emotion and playing style of a live orchestra.
My only criticisms are that the solos can come out a bit, and the lower end (cellos and basses) needs to be more present. I'm assuming that all these sounds are produced by a software instrument, but it still sells the atmosphere very well.
Don't forget to add dynamics to the soloists, especially the violin melody (or firsts in this case). My personal preference would have a solo violin, since I'm a violinist, but these are all up to interpretation.
I could see this playing in a movie or the end credits of a thrilling video game. Very well done.
