That's pretty good, perhaps a little tuneup on the strings is required but I wouldn't know. There again, perhaps the room you use is somewhat acoustically damped especially when full of people. I see the orchestra have a fair quantity of music on YouTube.
What I do remember about a university orchestra in New Zealand, after hearing them practice a number for Christmas over and over again, is that I never recognised it until somebody told me it was actually Prokofiev's Troika from the Lt. Kije Suite. It was dire but we were too polite to say anything to the players.
