Cool image with the swirling water and how it matches her pose. I know you are hearing this a thousand times about the shadows around her face and hair, but it hinders your image and your image is a good one.
I really like this photo. I am confused by the water on the lower left side because it seems to be plastic or something. But the shot is just spectacular.
She looks very grumpy, like someone threw her in there. :) The lighting her is a little flat - perhaps an overhead shade could help, or a reflector to reflect some nice light onto her.
very very well done 10
edited to add: that I still think that this is outstanding, i love the tone that you choose to go with, it really gives it much more of an impact than if it had been in colour. Sometimes the classiest poses are the simplest.
