Beautiful image.

Flesh tones are always difficult. There is such an incredible depth of colors. See this article http://airbrush-guidance.com/airbrus...rangest-colors

And here is a good but not very deep palette colors http://yatsu.deviantart.com/art/pain...tones-25750964

Skin is almost translucent with a pale blueish or greenish cast and deep red and purple shadows.

When I was in art school, I was always terrible at life drawing. In one class we were painting just the face. The model was an older woman.

My painting was terrible. My colors were muddy and dull. But as I was looking and looking and looking at the model and trying desperately to see color, any color, suddenly, the colors in the models face started to come alive and I could see deep red inside the nostrils, a greenish and bluish tint to the skin, along with pale yellow and soft pinks.

The shadows under her eyes were lavender. It was like a drug reaction except I was not taking drugs. It was an incredible experience.

Unfortunately, it did not last and it never happened again.
