I confess that I am inspired by Madge Gill (1882-1961), who did hundreds of ink drawings of faces on small cards during her life time. This face and the one before, Circus Day, were both inspired by her style as I see it.
The eyes of most of her faces are much farther apart than realistic and she always had the hair or head attire covering their forehead. Those were the two things that struck me.
Madge Gill faces had no shading as she only used ink but they all had such obvious personality.
