The first one is definitely better when you have changed the license plate but it still grabs the attention too much from the couple. Maybe it could be desaturated a little/even the yellow color changed or something so the plate wouldn't 'pop' so much?

The depth of field blur on the second looks good to me, much better than the original I would say. Is it done with the new blur tools in Photoshop CS6 beta? Maybe even a little bit of a fake miniature feel to it but I like it still. Overall the image is maybe a little greenish? And also it might look better if it was straightened in relation to the manor in the background that is leaning left a bit.

Hope my comments are of some help!
