I'm not really a fan of "it only looks overdesigned cause its supposed to be alien to you!" That they did with early Disco klingons and have done so far with SNW's Gorn. That line of thinking works for one off antagonists like V'ger, but these aliens are effectively supposed to be recurring characters and and making them and thier ships big balls of (sometimes asymmetric) noise means they all just start looking uniformly chaotic on top of being hard to replicate and recognize outside watching the show.
