He-..... err "she" looks like either a girly man, or a manly woman....... I wouldn't have even known it was Kitana unless it said, and his head looks too small....
Your artwork is very unique. It is not like a normal image that you see of a character, which makes it look better in my opinion. The way that you use shading and shadow, while still making Kitana look two dimensional is strange. While it isn't neccessarily a bad thing, it is just unique. An example of this is how the clothing doesn't look like another layer, but more like it is painted on her.
Also, the hair doesn't look like Kitana. I personally prefer the long ponytail that Kitana has (like in MK: Deadly Alliance), but that is not saying yours is bad.
Overall, I rate it 8/10 - there is something about it that is appealing, but it is also very different from the normal. Good job!
