I finally finished all the woodwork on the compression ring (on which the sky dome sits), all the tongue and groove pine and the finish trim between the ceiling segments 8' down from the top. The rest of the ceiling trim has to wait until the wall trim is installed as the ceiling trim butts to the wall trim.

The compression ring and trim between ceiling sections is blue stain pine (also known as beetle kill). The tongue and groove is #2 white pine.

The trim is not all done yet, but it's starting to take shape! Notice the wall on the left with the propane stove. Here is a closer pic of that wall:
