Looks nice . . . do you track the drums with the plexi, or is that just for rehearsal? I think you'll get better results without, also if you pull 'em off the wall a bit. The piano should be tracked away from the wall too. Try to get symmetry in your mix position too; you have a wall on the right but not the left.
I can't tell what's going on with the ceiling--is that vaulted, or is a floating cloud?
