I also do special effects makeup and work for Cinema Makeup School. I go to San Diego ComicCon each year, and have created a few makeups over the past decade there. In 2017 I partnered up with Strange Dave and Gabi Gonzalez to create the Arkham Asylum Joker from the Batman: Arkham Asylum video game.
