The sky appears to be fallen to the ground
All right, now, that's stunning. I spent five good minutes trying to find some defect, something I didn't see at my first view, but I couldn't find anything. I love the colours - soft and muted, they give a cold, melancholic, painting-like feeling to the picture - and the brightness of the clouds; the way they're reflected inside the water is marvellous. It's difficult to take a good photo at reflected skies, but you were able to do it for such a stunning effect. My compliments.
