David: Thanks for your comment. How true! Indeed, I took one of my favorite photos for just that reason: to see if I could make it better. My initial assessment is that this experiment did not drastically (or even marginally) improve the original. (I went through a dozen different attempts before picking these four finalists.) I plan to wait a day or two, see what others (such as you) think, and review these four to see if my opinion has changed regarding improving the image.
