Over all, all lines lead to a point outside the frame, the road , the line of ridges, even the approximate line between the ridges and the sky. The image makes me wonder "what's just outside the frame that is so important everything points to it?
In response to some of what is written above, I shoot many of my landscapes with polarizers. But from my point of view they are largely a lens protecter. I've been in a couple of situations where turning the polarizing reduced lens flare and regardless of what folks say, in some situations ambient light entering the lens at odd angles can be an issue in some images, and polarizer help with that. I'm not going to take mine on and off, so the choice is occasional banding and un-even skies with it on as opposed to occasional loss of micro-contrast and flaring with it off. From my perspective, the balance weighs in favour of the filter. When it does what it is designed to do it results in better micro-contrast, contrast and colour. But one way or the other, it makes a difference very rarely. Most of the time it's lens protection.
