You can keep lightening as you go with very thin watered down mixes. We used an off-white called Stencil (Ref: 70.313) from their Panzer Aces range. Just use the lightened highlights on the cheekbones, eyebrows, chin etc. Basically, anywhere not in shadow.
Add some red to create a darker fleshy tone - here, Hull Red (Ref: 70.985). Use this in the cheek hollows & on the lips. You can also use it in areas of mid shadow like the inside of the ears.
Make an even darker mix using German Camouflage Brown (Ref: 70.822). This is the deepest shadow, which can be used very sparingly to create the shadows either side of the mouth, under the lips under the brow above the eyes as well as for eyebrows. Again, here, thin watered down coats are the key.
This is now your basic foundation. You can keep taking the base flesh mix, lightening until it is almost white or darkening until it is almost brown or black & gently applying shadows & highlights. Subtlety is essential. Seal with matt varnish & then keep on going in progressive applications until happy.
Use the darkest mix to add a line under the eyes where the lower eyelid would be.
Finally, we added some highly diluted brown to show the goggle marks on our French tanker as well a bit of stubble & facial dirt. We did say we like our figures dirty! Just seal with matt varnish before tackling the rest of the figure.
Have a go at trying this technique on your figures’ faces. We also filmed this figure being painted, so if you are interested, a step-by-step video will be released soon.
