I've taken the last few days to work on some portraits to work on faces looking not only good, but similar to the person they depict. My original intention was to use different celebrities so that the person viewing could guess at the subject, but this pool comes from a somewhat limited range. I'll probably be going out of my way for more variety in my reference in the future.
It was also an exercise in working with vine charcoal. You can see a slight change in techniques from high contrast to something a little more traditional as the series continues.
