Wow! That is such a precious photo, you did an amazing job with this, it would be perfect for an advertisement of some sort if it hasn't been used for one already. This is a very powerful photo and is hard to look away from once you get a good glance at it, brilliant work.
I like the pose and the shot! The composition is also great. It would be nice to see this picture with a slight higher deffinition of b/w contrast. It's a great capture of the moment; as if she is frozen, waiting to exhale.
