She is the only one standing, and she is already the natural point of focus for the eye. Therefore I'm struggling to understand your decision to use such heavy Gaussian blur. I'm really not sure that it was necessary, the picture was strong enough to be left alone I think.
That's just my opinion many others may disagree and find a bewitching dreaminess in the image, perhaps a different approach might be to use white vignette instead.
I disagree with Curly on this one. I like the dreamlike effect created by the blurring. It makes the image somewhat thought-provoking, rather than merely documentary.
