Hey Tom, I have done this same thing recently. I had a shot of the Merced river in Yosemite that I processed about 3 or 4 different ways. It was really fun for me to do. It definitely is good to stir the creative juices.
I added #'s so it's easier for people to pick out favorites, I hope you don't mind.
I do like your original. With your edits, my favorite is #4.
You might want to add a poll to this, it's fun seeing Poll results.
