For many years I've practised the regular discipline of life drawing to sharpen my skills at drawing from observation.
Using a limited palette of Lead White, Yellow Ochre, Light Red and Lamp Black on a tinted board I use Sight Size to ensure an accurate rendering of form, tone and colour.
Drawing with the brush rather than outlining in pencil creates brush marks that are fresh and expressive.
The tinted background often acts as a shadow tone on the flesh which you can see throughout the painting.
This is a much quicker study than usual which has a very lively feel.
