It's alright...
Now don't get me wrong here, but what Delinquent said down there was partially correct in what he was saying (he's just a straight forward type person). Both you and the girls flows are decent but the delivery by the girl felt kind of bland where yours was ok. The beat is also decent at best but it's not something that would blow my mind away.
I do like what you're trying to do with this track so stay up and keep working on it.
