youve got many colors that can be used much more than how you have them now. also, youve clothed the figure so much, that the proportions are unreadable, but they are very off. my edit is still way to exaggerated to be even slightly realistic.
No, the cape looks sexy. The whole problem is that it looks like there are some many Lavender Blobs made through dithering. If I can edit the face I can try to give you a good idea how to do that.
