To me it has a post processed look. Don't know quite how else to describe it except to say that having done a zillion or so photos myself, I recognize it now in other people's photos where a person tried to get something that wasn't there in a photo. Probably from pushing the contrast a brightness up a little too much, to the point where the photo doesn't look natural anymore. Mostly in the left half of the photo, where the boat doesn't look quite right.
Looked again to try to put my finger on it, maybe this - look at the grass in the lower right, where it's fairly well lit, and then look at how dark the shadows are in front of it. I think you would expect to see more detail in those shadows given the amount of light on the grass. You could find a similar large variation in brightness on the boat, the bridge versus the dark area under the boat. So I'm thinking you need to throttle back on what you did with the contrast and probably brightness.
