Great scene Paul
I think the foreground object is integrated very well into the scene, great stuff!

Hi Richard
The project was rendered as 4000x2000 pixels, detail of 1.0 and AA of 14 with sampling level of 1/4 first samples, pixel noise threshold 0.01 making this a max sample per pixel of 196 and min of 49!!! I had done a GI cache file with relative detail 2, sample quality 2 and blur radius 8 (nominal values). I adjusted the AA according to some tips given my Tangled-Universe in his Terralive webinar a month or so back.....very good conference for those who were not there and you can get it from previously published links.
You might wish to see some of the artifacts obtained during render for which I have no explanation: http://www.planetside.co.uk/forums/index.php/topic,15798.0.html
Take care !

Wow, insane settings
You might perhaps go through the AA part of the webinar section again, because the settings you have used now is what I didn't recommend? or normally would recommend.
If you look at the AA-comparison sheet I made you can see that for those objects and situation there's visually not much difference between pixel noise threshold 0.01 and 0.04. The only difference is rendertime, almost 2.5x faster with PNT 0.04.
If you go to the AA settings and change AA from default 2/3 to 8 then you can see the PNT change to 0.0375.
This probably means that with AA8 you can remove noise to a PNT of ~0.0375.
A lower PNT requires more AA samples then if you follow those hints.
If you feel up to it, try this and compare in quality and especially rendertime:
Render detail 0.8
AA16 @ 1/16th first samples, noise threshold @ 0.025, Mitchell Netravalli filter. (now you're taking a minimum of 16 samples instead of 49)
I expect a 2x, maybe 3x faster render without noticeable loss of quality.
