When I set up the trophy room, I spend a lot of time on what trophies go on which pedestals. I'll get all the necessary ingredients, and just quicksave and try out combination after combination. Wild animals on the left and undead on the right? Trolls, bears, and cats? All short, all tall, or alternating? On and on. The one thing that always stays the same is the large plinth, dead center, the one you can see through the door, always gets a dragon skull. And I never equip the barrels and other crap. (Except wall shelves. I set those up and pile mammoth tusks on them until they won't hold any more.)
