Continuing work on the base layer, I smudged a few areas around bring out form. The first area I hit was the inside of the eye socket: I smudged a bit more shape into the underside of the brow, and made one strong smudge down the eye socket shape between the punctum and nose.

The second area I hit was the underside of the neck- an area that had been ignored a bit, was coming off as too dark. I made a quick spray with the lighter skin tone, and evened it out with some play from the smudge tool.

Continuing work in this area on the base layer, I used the polygonal lasso tool (at 4px feathering) to make a selection encompassing the jaw-line shape, from the bottom of the ear to the underside of the chin. I sampled the dark rose color from the upper lip, and sprayed the selected jaw area with a low opacity air brush.

On the multiply layer being used to add red hues to the cheeks and nose, I ran that same color over the upper portion of the ear. This could simulate blood vessels close to the surface of the skin, or burning from the sun (area with sensitive skin), etc&

I wanted to introduce a light sheen to the skin texture. Even though this texture would be used in conjunction with a specular map, I felt a light sheen would mix up the color a bit more, and give the skin surface a greater amount of tactility. To do this, I created a layer at the top of the stack and set the blend mode to 'soft light.' The airbrushed was used with a soft edge brush and low opacity, with a sky blue hue assigned. I lightly brushed over the brow, cheeks, nose, and neck, where I thought light contact would be the most prominent. This layer was smudged around until I saw fit, and then I moved on&
