I kind of dislike soft-focus-and-overexposed when there doesn't seem to be any reason for it. In this case, it feels like I'm looking at the picture through a dirty window.
My only minus about this image is that I'd like to be able to see the ground a bit more. I feel as though I'm craning my neck upward to look at this, and can't look back down. Overall, the tones are nice, and the fog adds mystery. Nice composition as well, other than the ground issue.
Nice job with this image. I really like the black and white effect that is added to this image. It looks nice with the fogginess that you shot the pic with .
