First of all, a fabulous portrait with an intense psychological connection between subject and viewer. There is an immense amount of depth in those dark brown eyes and those eyelashes...stunning.
I like the slight vignette, it added a lot of nice pastels into the image.
I enjoy the childish nature of the image. The wet skin, the biting the lip, the bright bathing suit. However, I don't like the angle. I wish you would have gotten down on her level. You eliminate her neck with the angle. It would be nice, as the viewer, to be at a child's level looking into her eyes.
Besides that, the image is great. The water-drop bokeh adds to all the little magical things going on.
