Wow!!!! Love these Graeme! You really scored with the conditions. I go back and forth between #2 and 3 as to my favorite. #1 is really good too, but I think the other two take it up a notch.
As I look at them more, I think with #3, I would lose that small branch with leaves in the lower left corner. I find that distracting. Clone or crop it out I think.
I think I will go with #3 as my favorite, I love the rushing clouds in it, and just behind it would be #2. The reflection in #2 is so awesome.
