I never had any formal art instruction. I don't know what I'm drawing till it's done.
And even then I don't necessarily know. I almost always draw directly with ink. The big exception was the Tarot cards in colored pencil on 3x5 index cards, then SmartBlurred (which I have since 'shopped hell out of and may post soon).
Anyhow, the top head is flat because I ran out room at the top of the page.
