Hmmm.... I like the concept, and it's a nice image, but there are several smal details which all contribute to an image that, IMO, while nice, isn't quite as strong as it should be. I'd have liked to see her moved over to the nice, even green of the bushes just slightly image left, and with that, most of the empty space cropped away. I would have preferred to see her left forearm not cropped either (both these issues could have been eliminated by shooting in portrait aspect! ). Don't forget to have her run a comb through her hair just to straighten it out; it's a little 'scattered' looking. The lighting is nice, but I think her right side is just a hair hot and her left just a hair dark.
Very nice Rosy!!! The exposure is spot on ('though you could perhaps dial back the highlights on the teeth just a tad), and the expression lovely. The only [VERY] minor nit is I think three catchlights might be a bit much; I'd clone out the lower reflector one.
