Your models are easy on the eyes which always helps in making a photo. The first model looks kind of tight, though. Was she nervous?
As far as lighting they look well done to my noob eyes. Also, the pp looks strong, but not overly-done.
If I were a mom or dad paying for these shots, I'd be happy with what I got. You made the girls look pretty, yet sophisticated. Very good, sir.
BTW, don't you think the second girl looks just like a teenage version of Angelina Jolie?
