To start with, none of the following art belongs to me. I just edited it for use in GalCiv3. No money is being made off the following assets.
That said, I've got some Dragonball Z races, some Magic: the Gathering stuff and some Star Wars. Use what you like.
And yes, some of it is awesome, some of it is so-so.
If you have any suggestions, go ahead and ask. I may not have time to get to it immediately, but who knows.
