I read in your bio that you'd like some feedback, so here it is. This is a great pose and the model looks relaxed and natural, which is half the battle. However, I don't think this looks as professional as the close crop (Whitney 1), the reason being that the setting is inappropriate. By including too much background it gives the photo a "snapshot in the back garden" feel. It's cluttered by the flowers on the right distracting the eye, and the leaf on the bottom left a distraction also. I would also have preferred a lower viewpoint and a little less shadow on her back. A gold reflector would have softened the shadows and really lifted this image. Finally, it's difficult to tell at this resolution, but it kind of looks to me like you inadvertantly focussed on her elbow in the centre of the frame and left her face slightly out of the depth of field? It may not be the case here, but this is certainly one of my failings, and I'm always reminding myself, "focus on the eyes!!!" If you get the focus spot on then you can get away with a much larger aperture. It would have been interesting to see the result at f/1.8.
