This is another version of the sketch I posted last night. Altogether I sketched this lady 13 times before I felt that I had done my best. Art, like any skill, involves a lot of practice and dedication for working on the things that are particularly difficult. It may take 10000 hours to be a master, but if all I draw is faces, I will be a master of nothing but drawing faces. Perspective and body anatomy are hard for me, so they are what I chose to spend my day practicing.
