From an alien species I drew a year or two ago, called the Elphinares. They're omnivorous, typically very mechanically-oriented, and are very quick and nimble. They're a sort of mix between human and feline and general extraterrestrial features. Their eyes glow to provide light for their tasks, and have a sharp tail blade that's capable of cutting. They are also typically antisocial creatures among their own kind, though they seem to get along fine with other species curiously enough C:
Though those are only some general species ideas I came up with when I created them! You're of course free to do as you please ^^
