There's nothing wrong with it anatomically as far as I can see, although there are a few things that I have a personal dislike for, such as the lips - it looks like there is either a lipring or some kind of line of makeup (or something) going down over her bottom lip. I dislike people messing around with lips in general, and I dislike liprings etc, so personally I find that detracts from any natural beauty she has.

She's lacking curves (the lack of thighs is a bit eh for me), but then, some girls do lack curves and this is a video game character, which also explains the gun which looks a bit too large - these are all things you expect with characters based on video games. Which I'm guessing it is? I don't actually know for sure.

In all seriousness, though, I'd love to see this coloured and if you take away my personal taste in women I see nothing wrong with it.
