Thanks for the replies guys. I think I'll leave this image now and start on something else.
Martin, you're absolutely right about the haze being noisy, I had Atmosphere on at 40 and the cloud setting at about 6 samples, I could of pumped it up a little more, but the way I did the water with PF, it would have taken days to render. So I think a little more R&D in that aspect is required to make the scene a little more render efficient. May come back to it when I don't need the machine for a weekend!
Domdib, I know what you mean about the grass on the cliff face, it was applied with a surface layer set at maximum slop angle, I guess I could use a paint shader to mask it out, but actually sort of like it there, I can imagine some nesting seaguls on the cliff face, or maybe it's some sort of algae growing there lower down. Anyway, thanks for your comments.
Cheers
Jon
