Subtle Colour Tints for the Gaul

In the last two sessions, I've concentrated on the area below the beard, particularly the shadows.
The darkest shadows require a subtle tint of red; the lighter shadows need a bit of orange mixed in. I'm supposed to add a small amount of Alizorin Crimson for the red and Burnt Sienna for the orange. I started doing so but more is needed. I also narrowed the overall shape of the neck and chest area before adding more detail in the lights.

To do still: finish modelling the base and then return to the head and make the light areas in the hair more neutral. They're too brown in places.
