Extreme foreshortening is a really important compositional tool—it brings hella drama with little effort. It’s also hella mindbending: getting that sketch remotely right requires getting your brain to disregard all of the stuff it knows (A FIST IS WAAAAAY SMALLER THAN A HEAD!@!!!!1!!!!😱) and just let the hand make the pencil scratch out what the eye sees. It’s fun, once you get past tearing your hair out.
