In this tutorial, we learn how to draw a skull with proper proportions. First, draw the outline of the skull with the light touch of a pencil. After this, use the pencil to draw two crossing lines that are the same length. Next, draw in the features of the face and head using the lines on the drawing. From here, you will start to add in the details to the features of the face and erase any background lines. Use the side of your pencil and the top of it to shade in the sockets and lines. To finish, add in cracks to the skull and lines for the bones and you're done!
