I'm almost entirely certain that I have never drawn the Predator before. Can't say that I know why. It seems so.... me. He's a great test subject to play with layering my washes, and I'd love a crack at the Dark Horse title (har, har). Hint: using a heat lamp at your art table can quick dry a wash without losing the distribution you slaved over. Conversely, even a small hairdryer will FUBAR* a well planned wash.
