A friend directed me to The Monster Engine, by illustrator Dave DeVries. He envisioned transforming children’s simple sketches into fully realized images full of color, texture, and depth:
The process is simple. I project a child’s drawing with an opaque projector, faithfully tracing each line. Applying a combination of logic and instinct, I then paint the image as realistically as I can. My medium is mixed—primarily acrylic, airbrush, and colored pencil.
He did an entire series this way, interpreting children’s art into finished products. You can see them here.
