Walls Primed, Ceiling Painted

Well, I got a lot done lately. After days of sanding and then touch ups and more sanding, I've finally painted. So... primed the ceiling and walls. And after that painted the ceiling with it's final coat of flat white paint. Will go through and look to see if I need to touch up any additional spots, as the primer makes imperfections easier to see, but after a quick look I only see a couple trouble spots that I've have to remedy.
Looks pretty cool as is though. I've have to decide on what color to paint the walls next...

I cut out the hole for the center channel speaker too, and pre-drilled holes for the tv mount.

Will keep the duct line painted white. 

Finished the hallway to the bathroom too, which is in darkness...

Mudding/sanding the duct probably took the most time.

And.. the back of the room.

A look at the fancy theatre lights finally installed.
