Then I learned...the loomis method!
It was handy and enlightening. And I referenced some pictures, which I’m sure I still have somewhere but I can’t quite pin down where.
I found the one for the heads on the left: Robert Marzullo’s tutorial.

Unfortunately I can’t find the other one I used, though I know it is a loomis tutorial.
Still, as good as these look, I still felt a little uneasy. They only looked this good because they were directly referenced. For example, almost none of those heads were original angles.
