for a title of "Sea & Sky", this shot encompasses far too much land. The bridge, too, becomes a primary focus that required me to look at the title to discover what opposite was being struck here. And I while I will certainly grant that trying to get rich, opposing colors out of water and sky can be next to impossible, having the only bold color statement in a picture thus entitled be the green of the grass completely defeats any other color statement that could have been made here.
I like the idea here - how there's a rugged landscape and then these structures that bind the two sides of the river together. I like the use of the right side tree to ground that side of the composition. I'd only suggest that you rotate slightly to counter clockwise to get your horizon straight.
You should look at my site and see the photo for Where You Live Challenge. Same Bridge. Picture is slightly downsloping to the right. Otherwisse nice shot.
It would be nice if the bridge went straight across the photograph, not at a slight angle. It would also be kind of pretty if the bridge was not in the center of the picture.
