Very nice. Always did like Tifa, and more for her character then her body, but I love the alterations to her costume you've added to give it the Dissidia feel. I could see her as a character in that game or any other.
And what seems to be an unwritten rule going on here, yes you look very attractive in these pics. But we'd probably only be friends at best.
Such a great outfit! Your shape and face really fits Tifa too. ^_^ And I know somebody already asked, but that couldn't possibly be your real hair, could it? If so, amazing. If not, you wear that wig with talent!
