Not sure about the DoF here - the near breast is mostly out the light and the far breast is mostly out of focus.
The problem is it leaves the viewer without a clear focal point to catch them and draw them in. I find myself looking at the area between her breaasts and of course there is nothing there for the eye to rest on. Maybe if you had gone for a different necklace coming further down her chest ?
I am not a fan of close-ups of body parts, but this one I do like. Great lighting, perfect DOF. The only (minor) point is the necklace. Otherwise, fine pic (8)
The necklace is a bit distracting and I am not sure what you were trying to accomplish with the sweat\liquid, but it doesn't add anything to the composition.
I guarantee that this picture will have more total views during voting than any other, even the top 10. I like breasts, but this picture does nothing to stimulate my gray matter...6
