Thanks, guys. That's the sort of comment I need, about the trees saturation. Any advice is always welcome. But it's a WIP, and mostly I don't do fancy stuff like soft shadows to test. Although in this next iteration I did. Took 90 minutes to render @0.65 AA6.
I don't know if the person needing this will be satisfied with the tree rows, as he's very vague about maps. I have to delve through all sorts of reports to find out what they really want. So it might change completely.
