You're getting your mileage out of that road!
I'll be honest, I don't know that this is one of your better shots. It's not bad, but...
The bright sun in the upper LH corner is a STRONG visual distraction, and pulls the eye away from the subjects as is the bright open area in the background. They're centred horizontally, which does work for portraiture, but I think you have a little too much open space on the sides; just a slight crop off of one side or the other would fix this.
Some minor details: her bra is showing, as is the handle of his knife, and his hand positioning is bleah. When doing this sort of composition have the man put his hands in the small of the woman's back so it doesn't look quite so much like he's playing grab-ass.
On the plus side, great job with the exposure on the couple!
Just my $00.02 worth - your mileage may vary.
