The domed head was better than the ridged head in my opinion. It surely looks scarier and serial killer-vibe, while the ridged dome gives it a more warrior-like. I liked Alien 1979 legs more than Aliens, because of its human-like feature, while Aliens have a more monstrous legs. The biomechanical features made us think of a somewhat perfect hybrid between biological and mechanical things, but also somewhat terrifying. The inner jaw and tail are cool looking, too(tail fin are only good in some case, like underwater scene, otherwise it wouldn't appeal to me).
