Step one today was to re-practice that initial head shape. @Lockenheim pointed out something vital and valuable to me on discord about my last ones.
Some of my center lines were not parallel to the center line and then it hit me how I was missing that. I had overlooked that the oval on the side of the head was of course a circle in perspective. Once that clicked (and with Lock's handy dandy reference in my document) it was a lot better.
Then I decided to get the jaw in and practice that too.
As always, Peace Love, and Progression.
