The lighting is just too even throughout the entire picture leaving the photo without any real depth. It is a very scenic spot and well worth a re-visit but perhaps at a different time of day when the light might play a more positive part in your composition.
Thanks for the comments Tex, I think the flat light is probably down to the
post processing more than anything else, not great in that department :) I
will definitely return there again at different times of the day also, it is not
too far away so I dont mind returning.
