Well, that got a lot out of my system.
I was trying to evoke the judges at the beginning of the Superman movie. As I stated, I like big heads. In among the pain gods you can see Arseface from Preacher as well as Dorammu from Dr. Strange, I think a few Muppets made their way in as well.
The Doc's coat and stethoscope were a lot of fun as they floundered around in zero-gee. Altering his garb from the surgical robe gave him a more dynamic physical presence. Much fun.
