The first stage is a basic acrylic covering, the colours do not need to be super accurate and this is especially the case with the flesh. In this case I have used Iraqi Sand as per a painting tutorial. Over the grey undercoat and surrounded with so much green he looks a bit Kermit.
Next up will be adding the oils and blending between the different shades. I have painted up a test on a spare head so have a good understanding of how it will progress.
I was quite happy with how the leather strap on the helmet worked out. Far less with the balaclava though this would look better once varnished.
