A few ideas:
Mic positions: Many VST libraries offer this feature but sometimes it's in the premium versions of their libraries (i.e. Platinum or Complete, etc). If your current libraries offer mic positions, then try selecting the close option.
Reverb mix: there's a lot of reverb, as you said. I'd experiment with the wet versus dry ratio some.
Panning: When listening to your track, I can hear a lot of the same instruments in either channel. This gives the illusion, at least to me, of being a listener in the back of the hall. Instead try and pan/structure your sounds like a conductor would hear them - up close and personal. Dbl basses to the far right, high violins to the left (if you wanted to follow that particular seating arrangement of the symphony).
Low end: Once the reverb issue is tweaked/fixed try raising the low end of some of the ensemble. Let your percussion really have some kick, etc.
Have you considered/experimented with the EQ setting on the actual reverb itself? That way there's a tail but not one that's super overpowering?
Are you applying reverb to every track? Even the master? I agree with your concern, it's washed out and could have much more impact with less reverb all over the place. Musically, the piece sounded great!
