Thanks for comments
Glad that you like the colors. Stalker armour derived from trencher shoulder pads and helmet. I made a crazy mix of 3 or 4 paints that I don't even remember now, fortunately I found VMC 70.897 Bronze Green - exact grey color as my crazy mix.
Actually, I have in my collection 1.ed. Venusian Marshal, perfect to paint mini based on another P. Bonner art, but pimped V-Ranger will be #9861, technically a Sargent converted to Captain/ Bauhaus Doomtrooper.
