You may be wondering why skulls are so popular in art. There are several reasons as to why this is so. Firstly, from a technical point of view, a human skull drawing offers great nuance in its complexity, complete with contrast, shading, and precision – this is no ordinary drawing subject. The skull is often depicted in a realistic way, and a skull drawing will allow the artist to get an in-depth understanding of their drawing subject. It has been said that the secret to mastering realism is to learn about the subject at hand’s internal mechanisms and structure, and you can do this with a skull drawing.
