Good job on getting both bird in focus with good detail, love the walking pose and the ripple created by it, nice catch light in both eyes too. Also like the green reflection color of the water as well. I like the idea of pano crop but maybe less of the left side and more on the right. Wish the shadow of the bird on the left didn't cast on the right.
I like Thanaboon's comments. I am not so concerned with the space on the ends as the space on the top and bottom. The birds feel a little centered horizontally - you might try taking a slice off the bottom and adding that much to the top so they sit a little lower in the frame and have a little more headroom.
Also - head angles are just slightly past center - not a death sentence, though, especially since you managed to keep the detail clean and clear in both. A tad more separation between them would have eliminated the shadow and a few steps ahead to your right and you might have caught the head angles right even with the focal plane.
Still...all those are minor points...it's a beautiful image and really gives me a sense of them as a couple.
Hif Folks; The devil made me do it - One suggestion, crop a little off the left. Other, take some off bottom & add same to top. Tried giving both suggestions, in a way. Gus
Glad you liked it Joel. Just gave it one pass of curves, Preset: Default-"Linear Contrast (RGB)" which is very gentle to make up for D/L, and slight deteriation of redoing. Does give it a slight pop. I often make that my last operation on PP my workflow.
