Hi headdie, welcome to the forums. Can you animate? Currently that's a big bottleneck for us in adding new aliens/civilian models, we could still use help with lots of things. If you have some shots of work you've done, I might be able to suggest ways you can contribute with models.
Feel free to hop on our IRC channel: irc://irc.freenode.org/ufoai
It's a good place to catch developers and discuss ideas.
