Very pretty young girl. There is a soulfulness and contentment you have captured quite nicely. The color green works well with her.
It is lit very well so that my eyes immediately look into her eyes. The lighting of her ear and hand are near perfection and the highlights in her hair bring life and texture
A couple of things I find slightly off.
The (main) catch lights are.obviously coming from the reflector below which puts them in the 7:00 o'clock position. Typically in portraitures, the 11:00 to 1:00 o'clock postitions are prefered because that is a natural position when we are out in the sun. However, there is a noticeable hint of catch lights in that poistion of both eyes coming from your softbox, camera left. If possible, I would emphasize those and remove the lower ones. Also, there is a third catch light in her left eye at 6:00 o'clock that doesn't have a dance partner.
Her left hand is distorting her jawline. The right side is beautifully shaped, but the left side seems messy. Possbily having her wrist turned slightly so that it does not make such a sharp angle and then having her place it underneath the jaw, a bit more symmetry would have been formed.
Lastly, this is just a personal opinion, a bit more of a lighting ratio would have given a touch more modeling to the left side of her face.
You can disreard all my ramblings because at the end of the day, this is a beautiful capture of a beautiful girl. Thanks for sharing.
