This is bunch of conceptual sketches of what Nian and anthro-moths body varieties can be.

Important note: fur, abdomen, muscle relief level and antennae don't relate to height. They're also normally supposed to be covered in fur, but I sketched only body carcasses for now.
I don't really plan to make any kind of catalogue, I just needed to practice different types of anatomy.

Nian (Space Station 14 race) are more anthropomorphic, mostly described having one set of arms, no insect abdomen, elastic plated body. There's no solid idea of what they should be like, because every game server has their own lore and biology of playable species. I tried three different SS14 projects and I started having my Nian around 2m (6'5") high majestic intellectual moth and then suddenly turned into 150cm (4'9") fragile, naive and a little more primitive species after transferring to another server.

I actually want to draw more insectoid characters too, so I tried to give some of them extra pairs of arms and abdomen. Abdomens look really weird though.
