Before layering muscle, a sculptor must map the skeletal rhythm. The bones of the arm act as mechanical levers that dictate how form shifts during motion. I can provide tailored advice on specific bony

The clavicle and scapula move as a single unit. When the arm is raised above 90 degrees, the scapula rotates upward, shifting the surface masses of the back and shoulder.

Before laying down clay or digital muscle strips, you must establish the skeletal armature. The bones of the arm dictate its proportions and limits of movement.

Motion begins at the clavicle and scapula. When the arm raises, the scapula rotates upward. If you sculpt a raised arm without shifting the shoulder blade, the pose will look "broken."
