Thank you everyone.
Tom, I should have said you "mentioned" AO, sorry. I've watched all those clips on Youtube, he's very good. That's where I got the settings for this render. I need to concentrate more on rendering as I don't seem to be able to produce anything consistent, mine always have a "cartoonie" look to them.
Edvinas, thanks for the link I understand now. I did the opposite and saturated the background!
thanks
John
