Thanks, Alexandre, I've been trying to get that black a little darker, turning out to be harder than I expected to find the right tool. I tried increasing contrast but it affected the bright areas too, and not in a way that I liked.

To me, the combination of the sun and graphical content is a little odd, but glad to see that others view it positively. I think an image like this is bound to create different impressions on different people.
