When the arm raises, the deltoid compresses into a tight, hard ball. When the arm hangs, it stretches into a elongated, smooth curve. 2. The Upper Arm (Biceps and Triceps)
For any artist—whether sculptor, 2D illustrator, or 3D modeler—the arm and hand are notoriously difficult. The challenge isn't just the complex bone structure; it's that these forms are never static. They twist, stretch, and compress.
The biceps swell, while the triceps stretch and flatten.
