I think the first one is the strongest here. love the silhouette and the golden hues. one thing that strikes me though is the proximity of the horizon to the pier. Somehow i wish you either moved up and got the pier way lower than the horizon or moved downward and got the pier far above the horizon. I think their proximity sorta negates both and stops either from standing out as they are fighting for attention. The shapes of the silhouettes work for me though.
