RE: Rapid Portrait Sketching - Mastering Likeness
Typically, I use this technique when I sketch people passing by, that is with exposure times very short or when I draw from imagination and I want to figure out a strong character personality. Besides, if you use this technique drawing from photo references, I recommend to have different angles of the head, because our brain must understand the overall volume of it. But, yes, to reinforce these ideas, and to convince unfaithful Verbal sketchers, a new post is necessary, I will built it. Theses ideas came to me when I got frustrated sketching portraits , using the verbal technique, and then my inner voice whispers me: "Draw head as a landscape". As a personal suggestion, @veryspider, as you have a very nice and loose hatching style when you draw drapery, and you also feel comfortable with graphic density concept my inner voice would tell you: "Draw heads like dresses". I know this may sound very very invasive, so, please excuse my inner voice meddling XD.
Your obedient servant,
Javier.
