Just found this via monoscope:
The artist David DeVries from South Orange New Jersey takes drawings from children as inspiration and redraws them in a grown up way. A really awesome collection of monsters and superheros. I wish I still had all my childhood drawings so he could redraw them.
Check out his website for more drawings: http://www.themonsterengine.com/art.html
Actually, this would be a nice little task at art school: »Bring one of you childhood drawings and redraw them with you current skill set« - Or something like that.
