Great fluid movement captured in the reflection along with a lot of brooding emotion. I've come back to this shot a number of times and each time it grows on me more - have to say I wasn't crazy about it at first. Her eyes are especially haunting. I don't know whether it's a trick of the stone, editing, or lighting, but it's really cool.
I'm so glad you posted that image in the reflections thread. I've looked at it a couple of times, but never read your comments. I thought it was just a PS effect. Now that I know it's a reflection, I have an even greater appreciation. Very moody, and great texture.
