Pam's sketches and explanations provided guidance on how to draw a face. This included information on the placement of the eyes, the positioning of the nose and mouth, and the addition of interesting shadows on the sides of the face. These shadows, where one side is light and the other is dark, added significant variations to the faces. I found it fascinating that adding a few lines or changing their thickness could alter the appearance of the faces in a significant way.
To create the faces, the code determines specific lines, areas, or points that are randomly moved to generate unique features. This process results in a diverse array of faces, each with their own distinctive qualities.
