I've started putting together the throne for the diorama. Yesterday I sanded some of the edges of the pieces - the bottom, and the sides of the back where there were some flaws from the casting. Then I glued it together.
Tonight I did the gap filling. Tomorrow I'll prime it, which will reveal where along the gap filling I need to clean up the edges of the putty. There's always spots that aren't integrated as smoothly as I thought.
