I had a student once who had a thing about feet. She couldn’t bear to look at them for any length of time so would do a quick sketch then focus on the hands or another part of the anatomy. I could sympathise. Other people’s feet are never easy to study for any length of time.
This sketch gives equal importance to the shadow as to the feet, and is not concerned with any detail. Rendered in Prussian blue it is built up out of lively brushmarks which capture their essence only.
