These doodles I had actually drawn back in July of 2018 while I was out at the Raleigh SuperCon convention, playing around with a number of design concepts.
At one point there, I sat next to my mom and I showed her a bunch of these doodles that I also inked at the convention. On the convention tables that were provided, there were some cheap sets of crayons: Red, Yellow, Green, and Blue. So my mom had taken my sketchbook and used the crayons to color in a few of the characters. X3
