Decided to try an exercise from Bernie Berlin's ATC book -- the magazine image exercise where you gesso over a face and then draw over it.
Here's a face from a clothing catalog. (You should've seen the ones I tore up and threw away -- this is harder than it looks.) I've enjoyed messing around with it, though, and realized how out of practice my drawing skills are. I have had fun learning how to use my Pitt drawing pens the way they're probably supposed to be used.
