Soft face drawing

I found this guy named Kyle Fleming on Instagram who has been a professional Etch-A-Sketch artist for over 10 years. If he didn't post the time-lapse videos of him creating it, I would think it was fake. Instead of using straight lines to do the shading, he often creates a grey scale by etching impossibly small, intricate squiggles. Zoom in on some of these pictures to fully appreciate them.
