The Sirren, first, I would like to thank you for taking the time to respond to the thread with your ideas. However, the image you posted, is at about the opposite spectrum of style I'm shooting for. Super over processed, tacky selective blurring (Obviously just my opinion, just trying to help you get a feel of what I'm shooting for here) and her dress looks almost silver now.
Also, unless you rotated it, flipping makes the tilt look even more extreme. Can't tell if you did that of it's just my eyes playing tricks on me. Either way, I don't like the idea of flipping the image, as the Bride and Groom will also be able to tell it was instantly flipped. Again, I apologize if I sounded harsh, I do appreciate your time, this just isn't the direction I'd like to go with the photo.
