This is the palette I am using.
This is where I was at the end of the first session. I had blocked in the rest of the square behind the crown of the hat with light blue to help me get the shape correct.
I adjusted the hat in front of the face. I also raised the eye and added shape to the lips.
I added black made from Cadmium Orange and French Ultramarine Blue to more of the hat to give shape to the face as well as the hat. I also began adjusting the ear.
I added some basic shading on and around the ear. I also added a bit more definition on the rest of the face and a few shadows in the hair. The back brim is also roughed in with black. Notice that I have not yet covered all the lines from the square I painted in the first step.
Before I began the third session, I looked through my books on drawing faces and made some discoveries which caused me work differently. I'll tell you about them next time.
