As an artist, you’ll have to draw turned heads countless times. But when the head is turned, drawing the far eye poses a special challenge. This is because we must foreshorten that eye more than we’re used to, and because we’re tempted to shape it like the near eye, which is less foreshortened. Therefore, it’s useful to practice drawing the far eye by itself, without the near eye to throw you off. Print these sheets, draw the eyes, and you’ll save yourself great difficulty later.
Note that all of these eyes are facing our left. You’ll need to practice right-facing eyes as well, so flop the sheets in Photoshop, print them again, and draw those also.
