>>6396334Hard to say. From aesthetics to colour scheme to type of armour, the Sardaukar are very different with each iteration. Personally I'd suggest a heavy armour/coat combo. Preferably either in a brown (desert) palette or a dark palette to look more menacing. The coat adds flair and ties the figure to the environment. Or maybe add samurai-ish bits.
Personally I'm a little limited on parts, but one build I was thinking was armored boots, Atlas thigh belts (thinner than vanilla thigh belts), Warlock skirt, Atlas Troop armour and backpack, Raphael's shoulder pads, Rappel Ghost arms, and the Tau-looking Warlock helmet.
Do you have anything with a lion on it?
