I usually pick bony protuberances as my landmarks when I'm drawing a portrait or figure. So the chin, or a clavicle, or a knee. Bones stay relatively still. Today, though, I struggled to get this drawing right, so the artist leading my life group suggested I try using the nose and left eyelash instead. That did help, even with the eyelash fluttering, but I ran out of time to fix the rest of the features. Fortunately, it's a two-week pose, so we'll see what next Saturday brings.
