Thanks, my way to paint flesh takes some work, but it is easy to learn. I use the paints: Humbrol 61 (flesh color), and artistic oils: burnt Siena and white. The first paint must be Humbrol, I tried different brands but this is the only one tested by me that doesn't get dissolved by the oil paint.
First, I paint the entire model with Humbrol 61 using airbrush, and let it dry for 24 hours. Then I paint the whole model with thin layer of burnt Siena, and wipe it with a soft hygienic tissues (or is it called handkerchief

? ). The artistic oils dry very slowly, so there is no need to hurry. The small details can be cleaned using cotton earbuds. After this stage paint is left in recesses on the model, just like wash but the translation between dark and light areas is more smooth. The final stage is white color - I add a small spots of white artistic oil on convex (sticking out) surfaces and then I smear the paint with large hard brush.
I hope you can understand it, because I had to use Google Translate a lot

I'll make a short tutorial during painting my next model.
