Hello, Crazor! Don't worry too much about mistakes in your bio, because most people have to make quite a few changes before their character is accepted. If you'd like any help with editing your bio, I'm sure that most of the members on here would be willing to give you a hand (including myself). Also, if you need some inspiration, don't be afraid to look at the bios of accepted characters!
Oh, and welcome to the site! =]
