I made my friend Cari Jo into a Jedi Knight. She's awsome :D
Hey! Mind if I offer a little constructive crit? :D
You've got a great figure going on... which I think the background sadly detracts from. While there's absolutely nothing wrong with keeping it simple, neither the colours nor subject do anything to complement her! It just gives the feeling of the cloud and bushes being a hasty afterthought rather than being treated with the same care as your Jedi.
For some fantastic examples of minimalist backgrounds that really support the figure, not to mention wonderfully balancing colour choices, I'd head over to Monkeyman's gallery.
