Well after many false starts on this idea of a bear sitting at a desk envious of the other boy's higher grade, I'm finally happy with a version. This is done with charcoal. I may begin replacing colored pencil with charcoal, as the line variation is much more interesting. Colored pencil line quality reminds me of a technical pen, and charcoal line quality seems similar to a dip pen. We'll see. Another reason I like charcoal is because it was my first medium when I began to take art a bit more seriously--around the age of 8 or 9. I drew my first successful 3-D 'sphere' with it and couldn't have been more excited.
