If you had been able to get them gently touching heads, while their necks formed a heart-shape, you would have had yourself a perfect shot.
So my honest critique would be ... sooo very close ... and yet sooo very far ...
Thanks for the critque.
I have one from a couple of years back with the heads in a heart shape, may post is later. Also have a couple in a beautiful courtship dance, and others, have not seen before.
