These drawings were made by Morgan Davidson who states that the eye and lips were sketched to keep her “hand muscles warmed up between portraits.”  So this was just a warm up? It is ironic because her facial studies are equally or more fascinating to look at, and I guess we should encourage her to do more stretch exercises!
