I like to think that comedic models will become common in future figure drawing sessions. I further fantasize that the best models...i.e. the funniest ones, the most fun to draw...will become much sought after on the art school circuit. I predict that we'll see a lot of certain types of characters. I'll mention a few of them here.
Well, there's the Mr. Meek type (above).
With costume changes the very same model could, in the same session, be a flamboyant dandy...
...a dancer or a singer...
...a snob...
...or a goofball...
...or a villain like Captain Hook.
She could also be a dancer (above)...
With a couple of pillows tucked into her clothes she could be a hefty post-middle age woman.
You'll obviously need a sexy bathing suit model (above). This requires someone funny who's voluptuous and curvy, not thin like a super model.
You'll also need a dramatic actress who can parody actresses like Garbo or Bette Davis.
