This document provides techniques for creating expressive and powerful pencil sketches through gesture drawing. It discusses establishing the figure's overall action and proportions through a sweeping line of action. Capturing the physical rhythms and asymmetries of the body is important to convey a sense of life. Drawing quickly and using varied line quality can help imply movement and atmosphere. Focusing on the line of gravity and areas of foreshortening helps indicate how the figure balances and moves through space. Master artists demonstrate how gestural drawings can establish vital foundations for later detailed works.
