Thanks for your answers! One more small opinion from me, if you care to read. About "boobs". My take, and perhaps many others' as well, is that it would be good to make the models better (like you do so wonderfully) and at the same time try and keep a little of the original characteristics of the original models.
Now, having big boobs is one of the characteristcs of Tifa and, how to say, make her boobs normal surely makes it more realistic but it loses something more important: identity. It's liike making Lara Croft's original boobs (Tomb Raider 1, I mean) smaller. I have always been against to making them bigger but liked to have them like they were the first time wa saw her on the original game.
Another example: perhaps we might think that in the future Cloud should look better without those impossible spiked hair. It would be more realistic. But just as for Tifa's boobs (even the colours seem so much more faithful in the former model, Borde), it would mean to create almost a new character. A character people that played the game before will not identify himself with.
Hopefully my feedback can be of some use to you, guys!
And thanks for everything!
