Shiny... want.
Well, almost. I generally like models better that are not too bulky or that don not look comic-like. I detest models that are supposed to be in action pose but end up looking static. Pet peeve: the good old left-foot/left-arm-forward position. We are talking humans not camels!
For fantasy models I'm a fan of "fantasy-realism" (if such a thing exists). So no swords that weigh a ton, armor so bulky people couldn't even think of moving their arms, overly ornamental armor that would make fighting near impossible etc.
