Ya know the more I use it, the more the lack of mobility in the elevator sticks out to me. I’ve got nothing but good things to say about the animation in Wicked. However, the elevator gears don’t turn and really stick out compared to how “alive” the rest of the world looks.
Just a thought, be cool if the gears were animated. 
Edit: oh and it’s not transparent when behind it either. Hiding the ladder to the house for sale.
