Undertones for Peyton

I'm starting on the undertones for Peyton today. I will keep layering the colors of Cinnamon and Burnt Umber to the point where I can start the detail. I have a few more layers until I get there. When I do the initial sketch for every portrait, I pencil in the areas where there is shading and contours of the face. With each layer of paint they come out more and I leave the pencil lines showing until the layers are filled in.
