I also decided to detail one of the upper rooms, which will hopefully show up well once the building is lit. I cut away the upper right portion of the main structure, then added a card-stock window seat.
The final step of the day was to put a base coat of black on the interior of the building. This will block the interior light, so that the walls don't glow once the lighting is installed.
