Some concept art for some aliens I've been working on in my head that I finally decided to sketch out.

Some details:

 - The aviin are a species from the arid world of Xyr, in the system of Mez. They are naturally cooperative, and culturally religious or at least spiritualistic. Many aviins see no issue with science and religion coexisting.

 - The ryvol are a species from the arctic world of Zyr, in the system of Mez. Societally they are very meritocratic, sometimes aggressively so. They have an unusual jaw structure and so they tend to wear rebreathers to stop people from freaking out.

 - The kydor are a species from the alpine world of Draz, from a system I don't have a name for right now. Extremely dimorphic as a species, female kydors are large and broad-shouldered, with a naturally protective instinct, and males tend to be lithe and agile and have a strong hunter instinct. Their naturally-matriarchal society is built as a martial dictatorship, but with no real class restrictions save those you can prove you belong to, usually through combat.

 - The zotan are a species from a jungle world I don't have a name for yet. Outside of them living in pack/clan societies and their unusual quirk of short-ranged teleportation, I don't really have too much for them yet.

 - The v'dak are a species that originally came from a tundra world that was destroyed by another, more powerful interstellar species. They are excellent climbers and have prehensile tails, and are naturally reclusive and individualistic. Their society, what little of it there is, focuses highly on specialisation and self-sufficiency, and for the most part each v'dak excels at one particular task.

 - the naeem are a synthetic species that were created by a semi-precursor race known for their affinity for robotics. One of the two major synthetic races they left behind after their death, the naeem are, ultimately, small but incredibly sophisticated AI cores that can be slotted into various frames to perform functions. Designed to be an assistant species, but one that could be self-sufficient, the naeem often try to anchor themselves to an existing culture and help them through their path, but usually for reasons ultimately unrelated to the naeem those cultures tend to die out. Naeem society is based around fleet-clans, said fleets being made from all sorts of salvaged starships from the many cultures they've attached themselves onto.
