Love the shading effects and colors. And the suit has some realistic looking folds in it, like its actually meant to fit a human being. I'm not sure this was what you were after, but it looks like she is licking her lips, as if she is spoiling for a fight.
Thanks for the comments, I've been working to improve how folds look in the clothing and costumes I paint. I wasn't trying to make it look like she's licking her lips but I really like that you see that in her expression.
