Fun Fact here: My wife just watched all six Star Wars Movies. The deal was I had to watch "The Note Book, Dirty Dancing, The Breakfast Club, and Grease." That way our marriage was equal. Truth was I was drinking watching her movies. LOL Your Leia Looks Awesome!!
I think having some kind of background would make this look better, since right now she's just floating in white space. Although that's not to say I don't like what you drew, because I think it's fantastic; I just think it needs to be connected to something.
I love the way you shade things - the purple hue works so freaking well; it always impresses me. It makes everything pop a lot more than staying with a brown color would. I also like the hair, it's so glossy and perfect. Everything about the way her body is shaped and how she's posed is really fantastic. It's hard for me to look away long enough to write this comment.
