It's always nice to see an orchestral%uFEFF piece, especially one as well done as this. ^.^
The movement at 1:46 is lovely, but I feel the samples dulled the full effect of the solo viola, and made the low end of the mix a bit muddy. The transition at 3:23 is awesome, and I loved the sliding strings throughout that movement. :) Loved the celesta @ 5:46, very nice touch to the end of that "cold" movement, but wished the french horns were an octave higher during the theme afterwards.
Overall, the orchestration was extremely well done, but the final mix was limited a bit by the samples used. You still get a 10/10 for producing amazing music though. ^.^
