Most of SWRP character are human. This is a bit odd for Star Wars, but understandable for Second Life. Human is the starting avatar, it's free, people usualy do their first visits in human avatar shape, also, its easy to play a human. People wanting to play another species need to find the avatar already made and pay it, or have the skills and time time to make something correct. Furthermore some sim are picky on the avatar quality.
So, I'm doing few avatars, the last one, is this female togruta, inspired by Shaak Ti. Someone wanting to play it would probably need some extra jewelry as they're used to wear some on their face. But it's easier to find or to do something correct in Second Life.
Now I have her made, I need inspiration to create a character with.
