Thanks for posting all four photos. It makes it even more interesting to study the different compositions available from the same spot. Surprisingly I do not have a favourite and any one of them does justice to the scene and the area.
The landscape here is stunning, and well worth a visit, and I like how you have included some of those visitors in your compositions, as well as other man made objects such as the viaduct and houses in the valley. Many landscape photographers try to avoid this like the plague, but if they are in close proximity, then I find it interesting to show both and their symbiosis, juxtaposition or encroachment.
