Bonjour
Your sentence is false ...
Either it's = Oh! Quelle fille ! ==> Oh what a girl she is ! ??????????????
OR
Où est-ce que la fille est ? ===> Where is the girl ?
Oh es ce que la fille est doesn't mean anything ....
first of all = "est-ce que" is correct not "es ce que"
"Est-ce que..." means you're asking a question ...
so something is missing at the end of the sentence ....if it's not a question ..
That's why I guessed that you might have said = 'Où' instead of 'oh' which means 'where' ....
Really hope it helps :)
