I am assuming that you have recorded the sections individualy and that should allow you to eq the sections. What I hear and mid you I am listening to an MP3 is that much of the orchastra is living in the same frequency area as the other instruments. try to alter the eq diferently on different sections and you may start to hear more of the instumants more clearly. The same goes for your vocalist, if you don't cut a hole (frequency perspective) in the mix you singer will get lost or burried no mater how loud he or she is. The tracking sounds very well done now you just need to get every body to compliment each other instaed of fighting for the same sonic frequency life
