This is my drawing. I used Arches cold press watercolor paper 140 lb and worked from a picture.

This is the first layer. I used only Yellow ochre (Da Vinci). I masked the face painting area because I will paint it at the end with pure colors.

This is the second layer, I used a Pinkish warm red (Alizarin crimson, Da Vinci) for most of the parts and some more orange-red (Permanent red light) On places I wanted a more orange color.

On the third layers I used also two different blues, a warmer blue on most of the shades of the face (Ultramarine Rembrandt) and a colder blue on the areas where the light was cold on the face(Prussian blue, Da Vinci)

In the last stage, I adjust colors where I need to do it, I scrub and wash away some paint where I need more light on the face, I soften some edges, and then paint the face painting.
