Great idea. I'd like to see it with a greater dof bringing the couple into focus, and with the flower off to the left into the (now) negative space balancing the statue.
I like the dof you have chosen to use. However, the picture feels severely off balance to me. The rose is in the middle of the frame (well, almost) adn the statues are in the middle and right, but there is absolutely nothing in the left. It is not enough to be effective negative space, I think, and too much to add to the composition. Perhaps if you cropped it just at the edge of the flower and statue-thingys, then "mirrored" it, it would feel more balanced.
Composition awkward. Not sure why you have the left 1/3 of the image - there's nothing there and the negative space doesn't add.The rose is in focus and colors are nice but not sure of your meaning here.
Image seems off balance. Lots of dark space on the left that really doesn't add anything to the photo. I find the OOF statue in the background distracting and the rose seems too centered.
