Thanks guys.
@ otakar: You're right, but in fact that's what these guys did. Take a piece of land, clear it, put a small levee around it, and plant something completely different. But is was in the pipeline to make different crops, and make some fields abandoned or less stark (some corners probably didn't grow well and were overgrown by weeds).
@ Marc: I much appreciate your offer, but I think I'll manage with what I have or make myself. Your refinement in trees would be invisible from this height anyway.
@ Jon: I'll give this a try, but I have to see how my machine behaves with these figures. I hope to render out at maybe 6000x6000px or slightly larger (the final print/poster will probably be 1-2m wide), but earlier renders of 5000x4000px stumbled and crashed occasionally. What do you mean by cowbell in the atmosphere? I was thinking of adding some very soft cloud to haze up the distance a bit.
@ Henry: I don't think blur would look natural from this distance, and I think the client wants everything sharp.
@ Inkydigit: That is indeed the problem, but I hadn't come to refining the tree pops yet. These are just 3 species with 0.6-1 size difference and some pop variation and a very rough mask. There will be more species and lonely and dead trees and such. The haze has been another thought indeed.
@ Cyber-Angel: There was no evidence of ditches around the settlements, and I'm not sure yet about levees around the fields. I put levees in, but they're not visible in this size render. By the way: I made the levees by subtracting a hardened (color adjust) mask from the initial soft field mask.
