No, I didn’t mean to base them of Inside Out, it just sort of happened. I wanted to make my own character in different poses and with different expressions. As I went to color them I figured it was easy to just give them the same color theme as the emotions from Inside Out.
No reference was used. I wanted to test my skills and imagination for the poses. The characters are painted in monochromatic style. In other words Joy is painted with different values of yellow, purple for fear, and red for anger.
