An interesting location, looks like we are on the attack from this viewpoint
The cloudscape is interesting but the modern metal framework at the top of the tower a distraction.
I think there are more images and a different viewpoint/time of day etc that may work better here.
I personally like the first image for its point of view - from a hillside little below. As Tim said it makes feel as we'd like to be invisible for the fortress guards. But you probably right, B&W could be better here.
