Excellent- number two leads my eye to the center of the frame best composition I think. First one has too much boulder center stage for my taste but the scenery beyond is great, looks like almost peak there in PA. Three and four very good shots as well, four a little cleaner shot as the dead tree competes for attention from the vista IMHO. I like the way the train tracks work in the images,especialy the second leads very well to center.
Here in Utah we are going to late season, mostly shades of gold- brown. Enjoy it while you can and get some wall hangers!
