I've been practicing a little bit of Willard Mullin this week. There's a great energy in his work that I really enjoy. His figures have a certain elegance about them, but they're still drawn funny and manly, in a way where the drawings are not drawn just for the sake of elegance. He seems to have an incredibly extensive knowledge of human anatomy, as well as cloth and folds. It's with this knowledge that he's able to draw the forms so loosely, and you can see that in his sketches. Unfortunately, I don't have the same grasp of information which Mullin had, but I think studying what he studied, and studying him with more carefulness is a good idea.
I didn't get the force in this drawing among a bunch of other things. Mullin's drawing is really incredible, the upper torso has a life of its own.
I can say much for this one too, but I'm going to keep trying.
Sorry about the cut and paste job on the pics, I have a small scanner and I'm doing these drawings on animation paper.
