Bummer the stage can't be extended all the way to the side walls (which I know is because of the door to the right and keeping with symmetry). But is there enough clearance there between the edge of the stage and the door? It looks like it swings into the other room, but it seems like a tight squeeze if someone is walking into the theater from there. Especially if it's dark - you're likely to trip right onto your 980's!
I do love the look of those 3D wall panels. I've bookmarked a few designs for my own dedicated theater when/if it happens.
