I think it's been programmed fairly well, the only thing that I would change is probably add a decent (but big) room verb to the entire orchestra track or group bus.
I know it goes without saying but the room size should sound like an Orchestra can actually fit in it hehe.
The snare sounded a tad bit dead but maybe if the orchestra sounds bigger it shouldn't even be a problem.
Try not to be too shy with the verb too. I'd suggest using
SepticFlesh's symphony's as reference (The song
Persepolis has some pretty good examples.
That should liven them up a bit and make it sound much more bigger! ?
