Dude, that is one awesome transformation... you are the man...
Have you ever thought about installing some better electronics in that room and make more of a theatre room... that would be the only thing i would change on it.. do a front projector mounted on the ceiling... a screen on the wall. I would have done it from the start and ran the speaker wires in the walls and mounted surround sound etc... that would be one bad ass theatre room.... it's still not too late.. but just a tad more difficult... looks like you might even have some speakes in the ceiling in a couple pics...
regardless.... awesome job man..... my hats off to you...
