Regarding the pose, is there any way you can build it to keep the joints adjustable?
Even if it meant loosening a few bolts to adjust the pose, I think I'd want to leave it with some articulation. That way you can have it standing in the living room or sitting at the kitchen table or riding in the car or lying on the couch.
Too many options to list really. In fact, now I want to build one just so I can photograph it doing all sorts of mundane things around town; pushing a shopping cart, riding a motorcycle, mowing the lawn.
Where did you get the kit?
