Sweet gift, Keith. They'll enjoy it a lot, and their family... Hope she feels better soon...
I'm amazed at the answers here...
There is no discussion, and I even showed it to other two friends who shoot portraits.
Number one. Not cropped.
The second shot is deeply sad: she looks tired, bored, and she's not happy being there.
Looking or not to camera has no importance at all in any photograph.
Even though he looks happier than her, in the first shot her face just says “old”, but the space (nature) and the happiness of the man with her, give the whole image a strong feeling of real trust and a well enjoyed life for both while being together.
The second one tells me he was feeling OK and she felt terrible.
Apart from all this, he looks a lot better in the first one, because if you are happy you don't look at what happens to who's at your side: you just smile careless like he does in the first shot.
Hope she enjoys the print, very kind from you.
Personally, I wouldn't frame two images, “unique” is stronger... Certainly I would do (family) more than one print of the same frame.
Cheers,
Juan
P.S.: I just checked them again, scrolling quickly up and down: both heads are strongly vertical like healthy branches on a tree on the first one, but on the second one their heads are "falling": the moment had just passed...
