Hello Matt, I made this drawing with a Prisma color col-erase on a Strathmore 400 paper. It was my first time with that pencil. I find it really indulgent but more difficult to reach a darker tone. On the left side of the hair I got lost with all the lines and shadows ….I guess I wasn’t squinting enough to get the overview of the head and focussing too much with the hair patern ? I find the right side softer than the left side.
