Shep Starts a New Commission

This handsome young man is my newest commission.  I've finished the drawing and am pretty far into the "Grisaille" stage.  As a reminder, in this stage the goal is to get Values correct.  I want to get the darkest dark's dark, and the brightest brights bright.  I'm always working on the drawing in every stage because as you see things differently as color is applied.  In this stage I'm using only Cold Black and Titanium White, Raw Umber and White, Black and Umber, and White.  The ears, hair, and hands are only in the drawing stage.
