Mr. black mask was ace. very mean, and the jaw did a great effect while keeping its simple and not cumbersome.
my problem with it is that the face under it is not scary, its just ugly. the red burnt like skin follows weird patters, the eye sockets are small and placed awkwardly, the jaws open sideways for some reason, and the lack of the crown over the dread roots looks bad. the red dreads were too over the top too.
the body has issues too. the armor is the opposite of the AvP's, being plain and lacking. only a couple straps across and an useless plate. no trophies, ornaments, only the bare chest. the absence of the netting made it worse. apart from the nice skin texture i'd say the bodies in Predators were very lazy work. i didn't felt they were threatening at all, i didn't felt they were properly equiped for the hunt.
