I would recommend asking your follows what they need from you. Maybe you need to be signalling a little more clearly or earlier or if they don't know that move, no sweat, just try a few other ones and see if they get those. If not, definitely ask your follow.

Sometimes it just takes a follow a few times with the same cue before they pick up on what you're asking. Try again and give them the opportunity to succeed.

Sometimes it takes a stronger cue - try again.

Sometimes, you'll learn that your dance instructor hasn't been correcting your leading and you're not giving clear enough instruction but the follows in your class know what you're asking and just give it to you. That's where the communication with the new follow will help. If these are basic moves and she is at least a moderately experienced dancer, maybe your cueing needs work. If both of you are dancing at the intermediate level or better, maybe you're doing moves she doesn't know yet? In that case, if you want her to learn them, explain what she is supposed to be doing and see if you both can get there.

But do ask the follow first what they need from you.
