Ahh! Wish I could visit greece.... love the windmills, but maybe it could have been more effective from a different angle? and to see some of the background, also.
I agree with lunarstillx - although it is interesting the way the wood supports fill the screen, I think more background would be a good idea. It also seems a little too "hot" or washed out. Last, it might not get as many downloads due to the odd size - I know I prefer images that fill the desktop.
I think this is an interesting photo, although -- like most portrait-oriented images -- not suitable for desktop wallpaper. As an experiment, you might try darkening the photo and then boosting the contrast a bit. I did this, and the darker blue sky which resulted seemed like an improvement to me.
