Inspired by this article on the facial plane that I came across while looking for something else. The first two drawings are versions of the image from the article. I attempted to reduce the variation between the faces though. I wanted to see what the difference looked like if how far the muzzle stuck out was the only variable. For the second set I googled before and after photos of an underbite correction. I remembered them from looking up the term "prognathic" which I had come across when studying skulls earlier in the year.
