Ron,
Number three is the one of these.
On #1, your light on the
model's back/shoulder is way too strong, and probably needs to be pulled back by one or two stops. Do you have the histogram for that image, and if so, can you post it? I expect that this problem should be evident there.
#2 almost works for me, but again, the lighting is a tad hot. Have a close look at this .... the
model's left cheek is blown, and the lighting is obviously quite directional, coming predominately from that side.
But now have a look at her right hand, and you can see that there, too, the exposure has been blown.
I think less correction is needed here - maybe a half to a full stop of power - but on its own, that's not going to be the answer, because
ATM the exposure on the rh side of her face is nailed, and reducing the power of your light source will affect that.
So ... pull the lighting back in power, and either add a reflector on the other side, or else raise the light's location so that it's not as directly from the one side - but that may not be the effect that you're seeking in this image.
hth.
