children's drawing into paintings

Here the original children works are more powerful than the paintings.

Dave Devries takes sketches of monsters drawn by children purely from their imagination and renders them realistically giving them a truly devilish look. His collection of drawings and paintings form a 48-page book “The Monster Engine”.
Devries would project a child’s drawing with an opaque projector, and then faithfully trace each line. Applying a combination of logic and instinct, he then paint the image as realistically as he can using primarily acrylic, airbrush, and colored pencil.

Says Dave Devries:

It began at the Jersey Shore in 1998, where my niece Jessica often filled my sketchbook with doodles. While I stared at them, I wondered if color, texture and shading could be applied for a 3D effect. As a painter, I made cartoons look three dimensional every day for the likes of Marvel and DC comics, so why couldn’t I apply those same techniques to a kid’s drawing? That was it... no research, no years of toil, just the curiosity of seeing Jessica’s drawings come to life.
