She's a 6/10, would shoot her but not book her for a week.
You need to work on your communication skills. You're not a "Playboy" shooter and neither is she a Playboy model. She's not a shy coy teen either.
She's a 20 something natural girl, shot by an "Amateur" photographer. So what's the fantasy behind the shoot?
Maybe a horny girl doing something she has always fantasised about and only just plucked up the courage, she's getting into it and the more she's doing it the more she's getting turned on and losing her inhibitions. In fact she's thinking about whether her pussy is getting wet and if you can see it.
Then she's thinking if you can see it what will she do if you make a move.
Take it on from there. By the end she should looking at you and showing her body in a way that makes the viewer think she's up for a fuck.
And you thought it was just about pointing a camera at a naked girl?
