The best photos of faces to draw tend to be photographs with imperfections, usually the photographs of yourself that you hate.
At least that is what I believe. It is far more interesting to draw a face if you have bags under your eyes from lack of sleep, creases, wrinkles or even spots. You may hate them but they add character to the face.
I’d much rather draw a normal human face ‘warts and all’ than airbrushed, caked-in-make-up, boring ones.
