We've mapped basic proportions and now transition to understanding the side plane of the head. This step involves identifying four points: hairline, base of nose, temple, and back of skull, to define the temporal fossa. Drawing is about sculpting, so we cut and add to approximate the reference. This process helps in developing features like the ear, jaw, and cheekbone, and understanding the structure and rhythm of the face. We'll be diving deeper into each feature of the face later, but this will be a good roadmap for you to see how we'll be using the steps we've learned so far.
