Beautiful shot, Louise. I love the idyllic setting and the romance of the newlywed couple, offset against the mare and foal enjoying one another's company.
The romance of this shot, for me, is underlined by the fact that the mare and foal have stopped their grazing or play or whatever in order to look at the happy couple, while the newlyweds only have eyes for each other. It provides a perfect point of focus for the shot as a whole.
There's not one thing I don't like about this image. It's perfect.
The couple walking away from the picture and into the lighted area and away from the shadow cast by the trees in great. It gives a sense of a bright future for the couple.
The two horses to the right gazing towards the couple is wonderful. It adds the perfect touch to the overall image of the photo.
