Here are a couple of drawings of Richard Chaves, done by a fellow RCappreciationGroup member, Rachael, in 2001. They're freehand and brilliantly done (sketched off of a paused frame from War of the Worlds - I'm so jealous). There's something so special about hand-drawn sketches of things, there's a quality in that type of art that really captures the essence of a subject, entirely differently than something photo-realistic would.

Rachael said "I made the page dark with
graphite, and then I erased the light parts." - neat technique, makes it look great!
