My sister-in-law called me on the phone while playing Giant Sandwich VS Princess Ballerina with my (then) 3-year-old niece, (who I assumed was the Princess Ballerina.) From what I could hear over the phone, my niece was using a "flying fist punch" to devastate the evil "Giant Sammich," (which was later described as a ham and swiss on white with flimsy leaves of lettuce.)
After that call, I imagined what that fight looked like and put it down on paper.
Crosshatching was used to build up the shadows. It's probably my favourite drawing technique. Works best with pen and ink. This is the cover image for one of my children's picture books.
