She was a fairly interesting character in the game, but I think it was silly how she had her jacket open like that all the time (Okay, so it's not a jacket, but English isn't my primary language and I kinda forgot what it's called) XD She did it all the time when she and Snake had just met, so I'd hardly think of it as flirting, either. Good game, but all the characters could've used more background and more personality, like the bosses in MGS1 did.
Anyway, as for the model, hard to say, really.. it looks pretty much like her, but since it's still WIP, I find it hard to really say anything about it, but I think you're doing well so far, keep it up and post some more stuff as it develops. :3
