Another old drawing. Not too old this time, just from late my junior year of college. I went through a strange period of being able to draw amazing hair. Then it went away. (cries)

This drawing didn't get too much updating, actually. I made things in the face more bilaterally symmetric, and filled in a few places in the hair that were a bit less amazing than the rest. I thinned down the lips a bit (they had been a bit redonk in the original drawing) and gave it a fancy border, but that was it. And actually, the idea for the border had been there. Here, see for yourself:

PS: Bilateral Symmetry is when you can draw a line down the center of a creature (for instance: Arthropods yes, coral polyps no.) and it will be the same, although mirrored, on both sides. The degree of bilateral symmetry has all sorts of fun implications for how humans react to other humans. Essentially, high levels of symmetry are hard-wired to be perceived as good, pretty, healthy, and trustworthy. Low levels, well... Igor. Quasimodo. All the bad movies you've ever seen where the guy with a limp or scar was menacing, and the scary lady you knew as a kid who you were afraid of because she had a port-wine stain or a large mole. (Yes, the one your mom insisted you be nice to.)

All of which is to say that symmetry is a very powerful tool to be aware of if you're drawing people. At stages during my process, I usually flip the image (either just using the horizontal flip command, or by holding the sheet up to a window so I can see through it) just to check for asymmetry that's too mild for me to conciously see.
