My hair was sooo pretty one day when I took it out so I took a picture of myself and my awesome hair. I wanted to draw a person so I drew that picture.
I found a different, more accurate way to measure a human using the cranium as a unit of measurement:
It's pretty cool. The cranium lines up with bones while the head lines up with exterior marks, like the naval. And the cranium is a sphere so it will always be a circle, no matter what angle it is at.
