Now, I am working on the legs. I have applied applied 4 flat layers of cream, pale pink, peach and yellow ochre, followed by an orange layer with which I have begun to model the contours of the limbs. On Joel's right leg, I have applied a first layer of blood orange, with varied pressure and curved strokes which followed the shape of the leg. In the following picture, you can see the difference that this modelling has made to the appearance of depth. There are many more layers to be applied before a realistic effect is achieved.
Throughout the process, I return periodically to previous sections of work to improve and develop them. It becomes easier to assess the progress of the work and plan future action when I can view each section in context with its surrounding parts. It, also, helps to come back to a section and view it with fresh eyes, after a few days working in another area.
