I originally pointed you to Arthur Mount’s illustrations back in 2006 when his work was primarily vector illustration. In refreshing the links I find that, in addition to his signature line drawings, he continues to explore other areas.
What caught my eye, in particular, was his series of portraits of Major League Baseball players, including the one of Khris Davis of the Oakland A’s above. The image is a simple GIF animation of three separate illustrations. I don’t recall having see this exact effect before but it does command your attention.
