These drawings exemplify knowledge of human anatomy, motion, and figure. Anatomy is the "building block" of drawing humans and animals. To a degree, one could say that environments have their own natural anatomy too. Understanding anatomy allows for drawings that are true to life and dynamic. Additionally, it allows for better stylized drawings. After all, the rules of anatomy can only be broken and exaggerated if first understood.

These drawings are multipurpose. Doing such drawings enhances understanding of not only anatomy, but also of form, weight, motion, exaggeration, perspective, shading, and line work. Throughout these drawings here, such elements can be seen.
