Oh goodness, Dare I get involved?! I've done some rather variety work before on aliens species before >3> Fluffy space raptors, wobbly gooey things, space dragons, space whales, I even made 'Equestrians' believable in a space-faring scale once. [I said 'equestrians' because there's not a single 'species' involved in that one] 

Just to clarify, I like to work the experience of not-so-obviously-human-like species in space, not 'because furry!', but because random 'kinda looks human but it's not because X random trait is present' has been done to DEATH by EVERYONE before.

It's so much more fun to explore the functions of entirely different creatures than it is to say something like 'these dudes look like humans but they're not... caaauuuse... oh! they've got gills, yeah, that's totally it... oh, and these funny looking lines on their faces! that too!'
