I really like the foreground image. It's very sharp and pleasing to the eye. I don't really like the background which looks like fire and also the photo in the frame should be in focus also. Perhaps have it at the mid point between the ring and the background?
The obviously painted background makes the shot feel a little fake. I would have prefer to see the white balance set to leave the lace more of a true white.
Normally love shallow DOF but here it does not appeal to me, I am pretty sure I would have liked this heaps more if the whole shot were in focus, I am just sitting here squinting my eyes trying to make out that couple. Nice job on the lighting though :)
I don't get the painting which monopolizes the frame. I can only guess the framed photograph is from the honeymoon? Bring the photograph forward (and into focus) and have a plain background and it would be much better.
Nice idea, sharpness in foreground, color in background. But too much of the image is out-of-focus, consider more DOF or composition for less vertical expanse.
