4th entry for July 2, 2012

These are some 5-minute studies above, a 10-minute one 2nd from bottom, and a 15-minute one below.

The 15-minute one is on a 22 x 30" sheet of Maidstone rag paper, done with hard Nobel charcoal on a gray pastel underlayer. The others are all on 23 x 34" sheets of Durotone Extra White paper.
