Vertigo –
I’d agree with Ken on this one. The idea is a good one, but poorly implemented. The castle is too small in the frame, and is not focused to boot – looks like the focus is on the reeds in the foreground and not sufficient depth-of-field to keep the castle in focus as well.
The small castle might have worked in a broader composition, but with the very tight one you posted, along with the lack of foreground interest it just doesn’t work.
