This course is designed as a comprehensive character design crash-course to help you learn and hit the ground running. You’ll get to experience my creative process from start to finish as I design the plucky cast of Zombie Bounty Hunters. I’ll explain every step along the way, so that you can walk away knowing the reasons behind each of my methods, and how you can use them yourself.  Over the course of four lessons, you’ll learn a holistic approach to character design that will give you new ways to think about your characters’ backstories, structure, anatomy, and much more!
