This is good "horizon" wise from yesterday's post, now from the name of the photograph if we have to consider the boat and fisherman as the subject, we have to say the subject is too far away. In my opinion this photo is very incomplete, if u had shot this in horizontal frame with more of those green leaves in the foreground and rest of the water and the land after that water, it would have been a nice Landscape photo. Nevertheless it is a very nice backlit situation, i think you have'nt utilized the best of the lighting situation of this landscape here.
I get a great feeling of serenity from this scene. The waves are peaceful and well defined, and the leaves add a warm presence because of the light. I have no problem with the composition, although the landscape in the background could be a touch darker (I think the light haze is a little distracting).
