In this tutorial, we learn how to draw a skull. First, select a picture of a skull that you want to draw. Then, sketch a few lines so you know where you are going to position the sockets in the eyes. Also do this for where you're going to position the nose and mouth cavities. Then, erase any unwanted background lines. From here, you will draw over your original sketch and then tone the eyes and the sockets. From here, you will tone and add shading to the rest of the skull and the areas behind it and you're done with the drawing!
