When making this project, I was thinking of all the proportional measurements I use to make human faces, especially the relationship between the eyes and the rest of the face. Starting out, I noticed that my random faces were just scaling up and down because the ratios were all established on one variable: the eye size. The end result is more interesting and resembles some of the steps I would make to draw a face.
