I have always liked drawing with wild pastel colors and finish with a black pastel on top. Then use a needle to put put the image. Off course it is even more easy on a devise, when you don't get all the mess.
I intended to do quick little spot illustrations for Inktober this year, but nooooooo! Now Jimmy is drowning in digital ink and lots of doodle details. This was way too much fun to go simple. I also included the original sketch this time.
