I wrote a rather long critique of these WONDERFUL pictures, but it got lost in the upload. #3 is a Phantastic Photo, as zardoz points out. In #1, I think you can crop out some of the sky, but all-in-all a very nice shot, with wonderful colors. I played with #4 a little in Photoshop. [Hope you don't mind; certainly if you do I'll delete my experiments.] There are many wonderful colors hiding in there.
