Too dark; yet it is nice to watch...the darkness accentuates the lone-ness of the pair; of course a vertical trim eliminating much of dark areas on either side can be an option.....
I like it. I am by NO means an expert or have any qualifications to judge the photo on any basis other than I like it. For me the darkness really gives the couple the illusion of being miles away.
Thanks for the comments. I have other shots that are tighter framed. I preferred to include the palm tree on the upper right. Thought it added to the tropical ambiance.
