Here's (above) a photo for comparison.
For comparison, here's (above) a caricature I've posted before. I include it here to show that John rarely draws people the same way twice. He's always searching for a new take on the subject or a new graphic technique.
Compare that to the way most artists draw caricatures. When the average artist finds a likeness that works he sticks with it and every subsequent drawing of the same person derives from the same template. Not John. He rethinks the problem every time he draws. Man O' man!
Last but not least (above)...My daughter's drawing of me eating a hamburger. Boy, that's a big nose!
