Gorgeous shots, all three. A wonderful smile in #1.
A few nits - very minor stuff that may be a matter of taste or preference:
#1. You could remove the barely seen left ear ring.
In #1 and #3, consider a crop of the bottom to hide the arm (and its skin folds) and keep the viewer focused on the face.
#2 could use a bottom crop too. I think seeing less of the garment at the bottom would be more pleasing. I understand these crop suggestions may mess with your photo ratios.
Such nice lighting! I'd love to know how you control the rim light on her left side. I have such a difficult time controlling mine from spilling onto the nose and also the harshness of it. It's difficult to find that sweet spot where it's a gentle soft light like yours... Any tips on setting this up?
