Okay, so I decided to take pictures and have made more progress today. I have the inner left wall up and most of the front wall. I have one more piece (M and N, specifically, which must be pre-assembled first) for the front wall, and then it's time to do the staircases.
Here you can see the turquoise. I decided to hold off painting the outside til I am done with the shell and before I add the trim.
