Thanks everyone! Perhaps it's not so obvious that it's a photo. But from my standpoint, with the real drawing in front of me, it's a bit blurry up around Rushton's head. It kind of makes him look like he has weird facial hair on his chin (which he doesn't in the actual drawing.
Apolo Ono, anyone? lol). When I have a chance, I'll probably upload a cleaner one.
Also, believe it or not, it's drawn with coloured pencils. The technique is fairly interesting, because I layer the color as one would with acrylic paint. First I cover the entire face with a solid light-ish skin tone, then over top add the highlights and shadows, and mix in other browns, golds, reds, pinks, and even greens. Black or coloured paper is always best, ideally it should be cardstock of some kind of non-fibrous paper. Otherwise, you run the risk of tearing the fibrous surface of the paper. This drawing was done on regular black fibrous paper, so I had to be very careful.
Yes, I paid special attention to the expressions. I'm glad they seem to convey the meaning I intended.
