that is a gorgeous view and it's perfectly framed by the castle window. speaking of frames that tiny green line between the actual image and the black border blends it much better than a white line. good color choice there.
i feel like i went back in time or something lol i was in that castle when i went to austria we took the same general shot.... but yours looks better all i had was a disposable camera you probably have a real nice camera. Great shot! brings back a lot of memories.
