Every child is an artist

This is a drawing of a little boy, used a reference photo of *Della-Stock, which you can find here: [link]

The original drawing has a darker charcoal background. I made a huge mistake by adding that background. I wanted to took the balance of the drawing more to the left, by adding more dark at the left side, because I drew the boy too much to the right.

Charcoal, derwent graphite pencils: 2H, H, HB, B, 2B,B
