Sketching a Face in Grey

When sketching a face in grey, I don't feel that choosing a monochrome space limits me. Whites, greys and blacks are the colour space in which to focus on the most important things we want to portray in a painting.

When sketching a face in grey, I focus on form, deep shadows and grey half-shadows. Although black and white are present in my portrait images, they are present more for contrast. They form a kind of reference to grey — the most important shade in these images, which most accurately reflects how life is — almost never radically white or black. Mostly — in between — grey.
