I'll start!
If you choose your door wisely, I will draw you a picture of a character from your comic/novel! 
DOOR #1: It's made entirely of gingerbread, with colorful gumdrops and icing adorning the edges.
DOOR #2: A plain, wooden door with a silver handle. There is nothing remarkable about it.
DOOR #3: A large door painted pale purple with white highlights. Moss is growing around the edges and out from underneath it.
