I also worked out a possible bench seat arrangement. The box over his head would contain a micro miniature diorama in plaster. the walls have the perfect recliner slope.
Also tested to see what size of plaster detail would fit in the lower section. Quite large actually. this is a 32" d container. In the center you can see the 3/4" plywood template this was a test to see if the template would hold the beams in alignment. So far so good.
