Anatomy is about function dictating form . When you understand that the biceps is a anchor that shortens, and the tricep is the antagonist that lengthens, you stop sculpting tubes and start sculpting functional machinery.

Sculpting the human arm and hand in motion requires a deep understanding of anatomy and a keen eye for detail. By studying the bones, muscles, and movements of the arm and hand, sculptors can create more realistic and dynamic works. Continuous practice, observation, and reference are key to mastering the depiction of these complex and expressive parts of the human body.
