I love your wig!!
But, I agree with Noose that your top seems a little tight. Also I would be careful to make sure that your bellybutton and soul gem are shown. I really love your color choices. Also it's hard to see in the images, but is your skirt cut at an angle? I think that's something that's really important in this character design. Also, pose wise I'd suggest a smile or two. (:
This is a great outfit! With a few tweaks it will be amazing!! (:
