If its possible i would shoot it again, morning or sunset and try it with a polarizer during midday . Your sky is washed out, and the building is a little dark with uneeded foreground. It could be a really cool shot.
Great shot but gotta agree that it would be better with a darker sky and lighter foreground, now it's your job to figure out how to do it!
BTW, isn't Croatia just North of the USA and slightly South of Canada?
