Beautiful. May I ask what colors you used for the skin and uniform?
Skin: Citadel Tallarn flesh, 1 highlight with a bit mixed in white
Uniform: That is a tricky one. I always use a wild mixture of the following Vallejo paints: 821, 824, 856. After looking at various historical photos all Desert uniforms seemed to be in various degrees of bleaching. So I deliberately change colours a bit. The technique for 15mm is always the same for me. Base colour, wash, 1 highlight in base colour again. 2nd highlight in base colour plus some white.
Done!
