Well this is my take of how Daphne Blake of Scooby Doo would look like. This occurred after babysitting my 1 year old brother who is crazy about Scooby Doo (the 1970s cartoon, not the modern cartoon which I distinctly dislike).
Materials used: prismacolor pencils, paper stump, gray artagain paper, stock image.
and link to precise image used: [link]
Time: 10 hours
**I smoothed out the image slightly with an editing tool, too remove some background "noise" Improvement was only slight.
