I agree with tirediron. I find many of my own images to lack "a subject". However, I do not think this necessarily degrades the image. When I encounter some type of spectacular light when out hiking or strolling in the woods, I do not need a subject to enjoy the scene; I take in the entire thing.
Still, it is important to compose the image properly. You could for example have cropped away some of the empty sky, which does not add anything of importance to your photograph. The image can sometimes be compared to a machine: all necessary parts should be included, and all unnecessary parts excluded. Or, if you prefer, the photographer could be compared to a reverse painter: A painter includes just what is necessary, while a photographer tries to exclude everything unnecessary.
I think the scenery is nice, but the lighting is quite dull. The lighting truly can make an image pop and come alive, and your image seems quite lifeless. Try to come back during a nice sunset, sunrise, or some other time when the lighting might be more interesting.
This is all just my opinion, of course.
