I like Judi's brighter version.
The water bottle can be emphasized and brought into the whole theme, or removed. I drink one bottle of Dannon Spring Water each day. The birds and lake add to the paecefulness. Great possibilites there.
I love the DOF here how it drags your eye to the bottom of the frame but the out of focus bird adds a little interest point to the background. I do feel that it could benefit from a bit more processing though, maybe using the levels command and shifting the slider on the right into the middle a bit more to brighten the whole thing up a shade. You caught the moment well but as someone else mentioned, it's a shame the resize killed the details in the facial expressions.
For one, I usually smart sharpen after the resize on a very low setting just to align the pixels a bit more and add a little touch of contrast.
Composition: I have taken the liberty to work with your image as y ou can see below. I have cropped a tad off the top as my eyes kept wandering out of the page. Aside from that I would possible have had a little more room around the main subject so they don't feel so confined. Love is meant to have no confinements...it is a free feeling, therefore you need to use your photo to convey that to the viewer. Make it so it isn't a feeling of entrapment. I know that it wasn't possible at the time, but in future watch for details such as the water bottle...very distracting to the eye.
Technical: I felt the image had flat lighting and worked it by increasing the saturation and then separately the greens. (All valid in Basic Editing)
Overall: I feel this had much potential. A little more experimenting with angles and lighting issues and this would have done much better.
good work on reaching your goal. Only cropped? When resizing, i would recommend always Unshaprening MAsk. Everytime you resize, you loose sharpness. USM is super practical. Good work.
