Thank you all for the nice feedback!
@danir: thx for the nomination
@ NateS: for the postprocessing i first used two differently exposed RAW files to get the light right in the sky and the foreground and used layers to merge them...
then I converted the shot to sepia with Hue Saturation, and and a copy of the shot to a more blueish shade that I only used on the water.. some levels and curves where used too
