This is a montage of quick sketch portraits of a female figure drawing model done over about 30 minutes. Each of the three poses was 10 minutes, and the composition was “on the fly” during the open studio and not planned ahead of time. I did move the first two portraits around until I firmed up the composition prior to adding sfumato and the third portrait but I did not resize or rotate the portraits.  A digital drawing tablet opens some really great possibilities for on the go sketching.
