that staff looks like a real sun bleached bone and the lips, knuckles and nose are spot on. Care to share how you did that?
GW Bugman’s Glow (i guess i used some GWs xD damn)
Vallejo Flat Flesh
Army Painter Barbarian Flesh
Vallejo Tan Earth
Vallejo Cavalry Brown (THIS IS THE BEST COLOR EVER! SUCH COVERAGE, SUCH HIGH DENSITY PIGMENTS. THIS MADE INTO WASH IS FENOMENAL!!)
Army Painter Alien purple
Army Painter Army Green
Army Painter Necrotic Flesh
Those are the colors i used the most for the skin (in general for the entire model)
Black Spray primer, then army green for the skin and bugman glow for the pink parts.
then a light, LIGHT, wash with that cavalry brown (and believe me, you cannot make it light xD it’s so dense in color) making all the recess warm and vivid
from there i started to highlight the army green + nectoric flesh, but i also added a tip of barbarian flesh to keep the model on a warmer tone and not a green rotten nurgle one (not not shiny green either)
at this point i made some shade mixing purple + cavalry brown in a wash again, that gives a realistic warm shadow that enhance those light contrast i built up by layering those greens
in the end i focused on the pink parts going lighter and lighter with pink, adding a bit of white AND that necrotic flesh, so i could still tone it a bit on the green side, without making it too vivid (reason why i used pink as base and not a mix of pink and red as i wanted this orc to be old)
the bone instead is much simpler. white spray can, 2 washes of bleached bone, couple of layers of dry brush with tan + white, then another light was of bleached bone plus, you guessed it, CAVALRY BROWN HELL YEAH 666, in the lower parts.
the cloth is a starting mix of doombull brown, of whatever gw warm brown is called + black, from there on i added vallejo tan earth so i could bleach it always more, and in the higher parts i focused on the wrinkles adding more white every time. never wetblend, but small layering adding everytime
i hope all this can make some sense, i always adjust what i do while i paint, so i never have an exact recipe, but overall this is what i did.
