This is where the course earns its keep. Most beginners (myself included) shade by guessing. Marc introduces the "Rule of 3" values (Shadow, Midtone, Light) and forces you to paint spheres and cloth without color. It's boring. It is also necessary .
You learn the "Bean" and "Robo Bean" methods. Marc uses muscle groups as puzzle pieces (Pecs, Delts, Abs). He draws the skeleton, then adds the muscles, then the skin. It is a constructionist approach. You will learn why the collarbone is the "hanger" for the shoulders. cubebrush art school term 1 by marc brunet
