Wow there's a lot to look at.........and that is the problem. Whatever crop/orientation you use, you sometimes need to force feed it to the viewer. When someone stands on a hilltop looking at the horizon, the brain automatically gets tunnel vision allowing it to tune out all that's around it and home in on specific segments. When you look at an image you're taking a slice of the scene, get to much and the viewer's brain becomes confused, it has no reference on what to tune out, causing the eye to wander trying to find something to lock on to. It's your job to decide what you want the viewer to see, so that when they first look at the image, their eye is drawn to the focal point.
My suggestion would be to use a 14x11 crop, put the top 1/3 line on the horizon. That will give you a bottom loaded image, with a cap of clouds, and more than enough details in between for the eye to discover.
