This is the FINAL stage of the grisaille (greyscale) picture. I have had two people tell me that I should leave this painting the way it is and not add color. Mr. Bill Martin over at Wet Canvas says this is your clue to let you know you've achieved the affect you want in a grisaille. It is the tonal map.
My next task will be to gradually glaze thin layers of color over what you see here. Stay tuned!
