For being burned out this piece looks great! I love the rim lighting to pop her out from the background! I like the soft light on the face from the right side and the hard light from the left. Also the armor looks really cool with all those tiny plates in it.
I really like this; the red and green in the suit is an appealing color scheme for her. I'm really picky about pictures with a red and green color scheme because of it's association with Christmas, but you really pulled it off. I think your choice of dark blue as the background is great. She looks so cool as is!
