This drawing shows the muscular tissue of the heel from below. It's a detailed and precise work. The artist used a brush and grey wash to create the image, and added white to highlight certain areas. The use of grey wash and white gives the drawing a sense of depth and dimension, which is interesting because it's a simple yet effective technique - check out the technique: cross-hatching, stippling.
