Dave DeVries, working out of New Jersey, uses kids doodles and drawings, and recreates them with a grown up flavor. His site The Monster Engine has been around for quite some time and has become quite a hit since is was first created in 2005. I love that he truly retains the essence and feel of the original doodles.
Yeondoo Jung, from Korea, takes the same idea but executes it in a completely different way. His "Wonderland" series explores simplistic shape focused children's sketches which he interprets into striking photography.
Happy drawing to all.
