Thank you very much!
It was shot handheld (eventhough I actually had a tripod in the car trunk =P), because at first it was just meant to be a travel snapshot of the scene...
Only after I imported the RAW file in my computer and started to play with the contrasts in the sky and reflections in the water a bit, I finally saw the great potential this shot has... =) I am very pleased with the result as well.
