Practice makes perfect, or arguably a little better. I wasn't happy with the results I was getting constructing heads, so I did a deeper dive into the subject. All of these are from imagination, although I certainly had reference books and Pinterest around to bail me out of the fire on the not infrequent occasion I forgot what a forehead was. There was a process shot in here, CoVid-19 murked it.
This project is best viewed while listening to the 'Too Many Cooks' theme song but mentally replacing the word 'cook' with 'head.'
