I signed up for a skillshare class: Comic Art: Introduction to Penciling for Comics. The first "homework" assignment was to draw a main character, supporting character, and villian.
Limbo is a young adult missing an arm (story here? probably), but content with his life. Roombo is the entity of a decomissioned robot and his broken Roomba. The android's legs are missing, and the Roomba's wheels are broken, so they help each other out.
I am still working out a villian.
