Quick and dirty. I tried to define as little as possible with actual line, wanting rather to define the form more with the value later.

I feel I could have eliminated even more line. It's certainly a safety net for me to define parts of the figure and lay down a "map" so that I have a safe guideline to follow as I continue.

God forbid I make a mistake and have to figure out how to fix it while coloring!
(that's sarcasm in case you were wondering)
