you are not the first mention this "aspect" of the shot. That dress was quite reflective and I have been debating a "tone down" of the area. In a way, it does have its own "quality" to it. I'll give it a go ... you never know until you do.
@Peter: Concerning the glass location ... I did have her move the glass through the scene ... trying to "find it" in the images ... and this was the one where it stood out the best. But, the weird part, as I was dropping off to sleep, I was troubled as how to improve the existing shot and thought I might just tone down the background ... to highlight the glass. It might have been cool to hit it with some kind of spot illumination, but ... did not have any to speak of.
