Above you can really start to see my process broken down into stages. In the first few layers of gouache I establish the light and dark contours of the face. The acrylic bottom layer of paint has a surprising amount to do with determining the overall feel of the finished piece. For example, will it be warm or cool, light or dark? This piece was just a super quick study in my sketchbook, but I included it because I think it as an interesting example of my process.
