Ah Ha! That's more like it Clive!
. Despite being such a small image, I can see it now has too much blue. A bit of colour balancing via levels in PS fixes it in a jiffy. See the before and after adjustment histograms below.
It's always a good idea to watch the histograms when your processing - this may avoid the red clipping I see at the black end of the red histograms - which implies you've lost some faint red signal.
