No roasting here!
I changed a couple of things, but overall I think you did a nice job.
I didn't want to change your character's style or her face, as I think it was what you spent most of your time designing. So I went into a couple of other things! As @Chris_Gardula noted, you rendered your metals without a metal texture, and your character is feeling quite textureless. So I slapped on some quick textures to represent that fix. I also changed the color balance, making the background a bit colder, as well as her metal, so her warmth, and her skin would stand out.
Values were also kind of weird. I didn't change everything that was wrong with it, but I tried changing things that would make the biggest impact. What stood out the most, was her sword, being quite gray and feeling as if it was in the way. So I made it pop, and that helped the picture. Always remember going into black and white to compare your values!
Other than that, I added a slight vignette and changed her left eye (which was tilting weirdly). Hope this helped!
EDIT: Seems like the pictures have more contrast on this site. No idea of why.
