Afraid it doesn't do it for me. It's a very good shot, and I don't think it needs anything else. The white vignette is too contrived, IMO. It looks as if the water in the BR corner is burnt out, and I'm sure it isn't.
Hi Shadowman, I did ramp up the the colours in camera as the scene was incredibly green when the sun caught it, so I was after that effect, though I did tone it down slightly in PP
I took the shot when the sun was hidden by the cloud to get as long a shutter speed as possible, I do agree it looks does look postcard quality.
