Step 10 & 11. I have added light yellow tones to the skin opposite the areas of direct cool light.

I've deepened the lilac shades of colour. This is where it gets a little complicated. The lilac areas are where the light source is reflecting off the side planes of the face and therefore they are cool in tone.

I've added some very light touches of crimson mixed with a touch of raw umber to the darkest areas of the outsides of the cheek, the shadow under and along the nose and under the chin and the shadow areas of the ear. I've also started detailing the eyes with eyeshadow and lashes and detailed the eyebrows.

I have continued to use short, brisk strokes with a round brush for detailing and deepening the areas of colour. I soften hard edges of paint with my finger as I find this is the quickest way to work because acrylic paint dries so fast.
