I've had this Frankenstein Monster figure from Andrea Miniatures for the longest time, now. It's a 1/32 scale metal figure. It comes with a doorway with a smashed-down door.
I added the wall behind him, making it out of Balsa Foam. The torch comes with the model, but I just added it to the wall.
Since it's 1/32 scale, the entire diorama fits right in the palm of your hand.
I also put a black piece of poster board in the opened doorway right behind him, so you're not staring out into empty space. The whole dio sits on a thick piece of poster board, which gives it a nice, sturdy foundation.
