I have finally been able to finish a large chunk of my Empire army and will commence on the Ogre Kingdom minis soonish. I have however tried out a color set and look that I am quite pleased with. Note that I am aiming for an army standard that looks good on the table but doesn't take all that long to finish (for me that is since my Empire army has taken a full year almost).
The skin is done with a more dark oriental look in mind. I started off with snakebite and worked my way up to bronze flesh (some five shades with a glaze). Then I finished it off with a Vallejo smoke ink.
The steel metal is done by painting it beast brown, drybrushed with light orange, highlighted with thinned boltgun and washed twice with medium thick Tamiya smoke.
The blood is done with a mix of scorched brown, red ink, blood red, and highlighted with thick Tamiya Clear Red.
Expect a butcher and four more Bulls with a week or two (first doing my Marauder Giant for my Empire army).
