If it can help:
A few other shots:
Late afternoon (low alt.)
Early morning (low alt.)
One thing I noticed as important to achieve a good result:
If I put a plane above the landscape, how does it look ?
They should fit well together, I think (planes camouflage colors should be in landscape color palette.
Another rule I found useful : to avoid as much as possible REGULARITY :
So, in a tex-pack I use for a map, there are some nearly uniform ones, others with large fields pattern, others with little fields pattern. Then, landscape are a patch of all that mixed together (some kind of pattern inside pattern
)
... I was so disappointed with CoD landscape
(btw, I don't know constraints to make a CoD landscape... )
