When drawing portraits, many art students face challenges because they lack knowledge of the head’s internal structure. The human head and face are mostly shaped not by muscles, but by the bones of the skull. These bones are fixed and stable; muscles do not influence their shapes. That is why good knowledge of skull anatomy is very important when drawing portraits. So, if your goal is to draw portraits, start with the anatomy of a skull. The sooner you do it, the easier your learning curve will be, and the sooner you will be able to draw proportionate and correct portraits from life, memory, or imagination.
