Sketching in pencil has really appealed to me the last few days, not because I feel the need to erase any lines, but because pencil sketching sometimes seems more tactile, simpler, basic. After I've done watercolor and pen for a while, the simple shading effects you get with pencil can look fresh and new again. However, in a timed challenge like the 20 minutes I spent here, you have to be conscious of getting a range of values in as quickly as possible. Pencil, approx. 5" x 5".
