I'm trying to work fairly light to get the basics down. He has a heavy 5 o'clock shadow and hopefully I can portray that. I will be applying more graphite to the background, to make it darker with a smoother look. This represents several hours work and will look at this upside down to see if the features are accurate. The mouth is the area that is giving me a bit of trouble. There is just a hint of teeth showing which I hope to indicate with a slightly lighter value than the upper lip while the lower lip is lighter because of the light.
