It is'nt that easy really! Fucking hard to get a realistic look of skin, whatever fucking skin it is!
Airbrushing the orc at the moment and everything was looking great until I happened to knock out pretty much of it with a darker tone. As always.. need practise :) So I'm patient.
Painting with airbrush is really really fun though and you can really get those insane colourschemes. More ppl should get one for themselves ;)
