I really like this photo as it is not just disguising the person themselve but it is also disguising emotion that the girl is feeling. It almost gives the impression of an explosion of feeling and emotion. It can also present the feeling of insanity.
I loved doing this in art class. Art With Mr. E: Line Design w/Shading - Grade Very cool, fun art shading project from Art With Mr. he's an elementary art specialist. Try this with your kids (but I think grown ups would enjoy this too).
