Here’s my latest comic: https://inhumaneresourcescomic.com/#/panel/679.
The Green Skull panels that show him in an empty space are done on a new file that I call “Caligari” after the movie the Cabinet of Doctor Caligari that had really weird, abstract sets.
Much of my inspiration for these bright, abstract scenes is the webcomic Move Me. I was really impressed by the use of color and its emotional impact.
