First off I must say this is a lovely composition. The model looks comfortable and confident. Which she conveys very well in her body language. And I love her hairdo in this shot. The ponytail coming down like that is marvelous.
Looks like you had late afternoon lighting since the highlights don't seem to be harsh at all. But that could also be the metering of the camera. But I do love how the lighting looks on her right side. Her Face is well lite and her eyes just jump out. If you used a reflector, a little more light on her legs could have been a nice touch too. But maybe the shadow from the right leg would not have been desirable.
Wonderfully sexy with just the right touch of class and elegance which help set this photo apart from your typical swimsuit shot. Nice bokeh from the background. The depth of field from behind lends itself to this photography. Yields an interesting contrast of depth of the subject to the background.
I like everything about this shot -- the lighting, the setting, the oufit, the model -- except the fact that her left leg looks amputated. As a general rule, you don't want to cut a subject off at any joint (knee, ankle, wrist, elbow). A magazine or photo editor would drop this image because of that fact. I would have tried something different with that leg, either have it stretched out straight and try cropping it at mid-shin or open up the composition a bit and include the whole leg. Fingertips are chopped off too, but that's not so big a deal.
