GMorrison - I know the helmet has just the initial coat of paint, but that particularly is looking smart. Also, great resourcefulness on you part in replacing the kit items.
P Mitch - a striking finish to Ironman, it really looks great! 
Bish - good job with hand brushing the gloss, and hope things turn out well with Vader's cape.

Red Sonja is still not back to the point she was, but the basic skin tones are now filled in.
1.) For the sort of pre-shading step, I kept things simple and just used an existing shade of green, Vallejo Olive Grey 70888. After an overall coat, mixed in some white and sprayed mainly from over head angles. Some further white and another round of spraying. Did hand paint some lighter tones on the face, but not too much as it would be covered later with proper flesh tones.
2.) I had been using Brown Sand 70876 as the base skin colour, which is what is seen here. Close inspection though showed specs of dust had been trapped in the paint, so after sanding them off, had to go to step 3.
3.) Mixing new paint, so used a combination of Red Leather 70818 and Green Ochre 70914. Second round of spraying, base colour is lightened with Basic Skintone 70815. This was followed with an even lighter application by mixing in white.
