Help picking cosplay

So, I'm going to cosplay for an animê convention but I need help choosing a character. I have long brown hair and hazel eyes, but I don't mind using contacts or a wig. Oh, and I'm tall. Here are some of the animes I watch, please try to choose a character from one of these:
-Naruto/Naruto Shippuden (maybe hinata from shippuden?)
-Toradora
-Fullmetal alchemist
-Lovely Complex
-Special A
-Death note
-Fairy Tail
-Girls Bravo
-Elfen Lied
-Chobits
-Zero no tsukaima
-Bleach
-Ouran High School Host Club
...

please help me, it's the first time I'm going to an animê convention and I'm really excited. Oh, and a friend of mine is also trying to pick a cosplay, if you want to help him too por telling me what you think, I would be soo grateful :D he's got brown hair and green eyes. Thank you ;)
