This is a warm up sketch where I drew some lines on the page and formed faces from them.

Pen, 5x8 in. 1 hr.

So I kind of threw out the idea of trying to memorize the face then draw it, I think what I need to work on is learning the different planes of the face. So I'm going to try drawing a few different versions of the same person on the same piece of paper.

Mechanical pencil, 30-45 mins.
