Kitana's Kiss of Death should be like this:
Kitana takes of her mask, kisses the opponent and walks back. The opponent starts puking blood, then puking internal organs, and finally he screams looking up like "oh my God, I can't stand anymore", then his head falls back and all his body crumbles into pieces.
About her hair, I think they will probably change it afterwards. Other things that I'd change: change forward dash to run, make characters scream more, make the ice white, not blue, have at least three fatalities per character, no babalities or animalities, maybe friendships and hara kiris, no mini games outside the fights, inside the fight there could be test your might mkvsdcu style, but this time with more variety (like breaking floors while falling).
