Thanks so much for all the wonderful comments. I think I'll just stop right now and call it finished! (just kidding . . . this is a Christmas present) In answer to your questions:This is my first attempt at detailed hair. Before this I really didn't put much work into hair, and it was the LAST thing I did. I got my inspiration for attempting this level of detail from this forum . . . thanks to Marc, MHK, Shelby, and portraitartist2002 among others.
This drawing is on low grade smooth Bristol. I used HB lead primarily with 2B added in the darker areas. My primary technique was multiple layers, with selective blending (stump) and picking out highlights (sticky kneaded rubber) in between each application of graphite. I also used alot of negative drawing in the darker areas, with a few lines inscribed (blunt end of needle) for the few "wild" hairs. I think the depth was achieved with the many layers applied, but I think I got dangerously close to over-working some areas (maybe too close).
