I am impatiently waiting for Mike Sibley's book "Drawing from Line to Life"! I bit the bullet and finally after drooling over it for 12 months, I did it! I know its not exciting for everyone else but I just love his negative drawing, and can't wait to see more of his methods with animal portraits and the scenes he places them in.
If you haven't seen his work before its worth a look at www.sibleyfineart.com . And he has a couple of tutorials on his site if you're interested.
