I think it's a great photo, and I'm sure the handsome couple is very happy with it!
The only small critique I have is that the image feels like it's tilted to the right? Maybe due to the strong slant of the trees and posts on the left.
So I cropped out some of the closest tree on the left and tilted the horizon slightly. What do you think climber?
Again, wonderful image and interesting technique!
Original and then my very small edit.
