making the aliens look less 'human'

remove the male/female roles in the art. Why would aliens have the same (secondary) characteristics as humans? Even organisms on earth with 'just' a distinction by x/y chromosomes, show various forms of these characteristics (e.g. feathers) and even then  can still develop different characteristics and therefore different behaviour. Some species are asexual, all female  (e.g. Ambystoma tremblayi) or reproduce en mass passively (corals, trees) . It is weird that the species in this game all have female breasts, even when they are virtual. Thus in short: change these pieces of the art and take some more inspiration from the real world. There are so many weird critters alive.
