With live drawing you are on the clock, and every stroke counts. Every mark either gets closer to the form or, like a bad subterranean guide, leads you farther from your destination, and makes it more difficult to find your way back.
Last week, I drew Dan and his wife, Andrea. As many of you know, I nearly became a geologist at one point in life, so it was interesting to hear from a working geologist.
Notes on technique: I decided to use both graphite and Conté crayon for Andrea's portrait, which is why it's a bit lighter overall in tone. It's an experimental effect, and one I might use again. Personally, I love the matte finish of Conté, as opposed to the shine of graphite, but each has a different range of effects where it can really perform well.
