I really like the image. The color version is maybe a bit over the top and the mono version looks great. I think there is probably room for a great looking color version too, maybe just toned down a bit.
Nice photo regardless!
OK guys, here are the last two versions (honest!) and from the input from you all helping me to decide which way to go with this image in its various forms, here are the final other two versions - possibly
I like the straight B&W version above and I also like the blown out aspect of it, which isn't truly blown out to 255 except in the sun area, I like it because it harks back and reminds me of the film days, where skies were often blown out, but which was seen as more acceptable and more unavoidable back then.
Firstly there is the toned down version to add a bit of reality back into the scene and then a combo of them all into a sort of mono and warm tone type of composite.
Thanks for all your help people
