Thank you for your comment, I am really flattered. And yes, I tried it out, a cropping would not have been had.
To answer your question: When I saw this picture the 1st time on my computer I also was surprised, as I did not see that blue spot so intense when I took the shot. Amazing, somehow.
I just took the picture, sized it down to 400k and posted it.
Nice shot dear Urs, I like the contrast in this shot and the over exposed sky. ( is the sky real or have you cloned it in photoshop or sth? it looks a bit strange!!) I think the overall composition would improve with the cropping of the bottom 1/5. Anyway, Good work, Well done. Regards, aLi
