Painting shadows is very easy and you see progress quickly. Therefore, you should never start by painting the shadows, before you have painted the lights. The reason for that is very simple, the overall look of the painted area will be too dark. I always start with the middle tone and work towards the lightest colour. After that, I use different tones for the shadows. This way, the light areas will dominate and make the painted area look more interesting to the viewer.
I tried a new mix of colours for the face, what is risky when you want to show something. The colours I used for the base tone are Bronzed Flesh, Flat Tan (Vallejo Air Colour), dark flesh and US Grey Light (Vallejo Air Colour). This mix is totally different to the tones I usually use. I want to reduce the red tones in the flesh because I aim for some kind of pale flesh. Not ill looking, but definitely not healthy as well.
After a few layers with the base colour, I had this result:
A few mixtures later (I added Bronzed Flesh and Elf Flesh to the mix):
More Elf Flesh has been added:
All I have done so far, is giving the face a very general direction. Painting up to now has been a pain in the ass, because you can hardly see any progress, yet this stage is very important for the final result. You don't have to care that much about blendings up to here because most of it wont be visible in the end. From this point on, I begin to work out the strong, characteristic lines and areas of the face, still only with lights.
