If you wanted to say "finished" at the end there in french, that's not how you say it. "Tu es finie." (Or "T'es finie!" With "Tu es" contracted into "T'es" in the same way that "you are" becomes "you're") Would be the translation. (Notice the e at the end of fini here, that's when you know the subject is a female, if it's a guy, you don't put the e)
