This is a very nice image. Her looking at the camera with the sunglasses is interesting and the b-w is a good choice. I would like to see the crop include her left hand, but this is a dandy image as you show it.
Church, that's a very attractive lady and the BW conversion works well. One thing I'll say, I think the focus point should probably be on her face. As it is, it is on her chest (notice how sharp the cross and bikini top are compared to her head), and I'm not sure if that's what you wanted to highlight (as lovely as it may be :wink.
I think either having the focus on her face or a smaller f-stop to increase your DOF and get her head in focus, too, would have added to the image. As it is, still a very nice capture.
