Thanks for the comments. I placed the camera here partly to check out the grass and tree distribution. I think it needs to be denser but that means more work on my masking and setting extra populations to reduce the rendering quality of distant trees to keep RAM usage under control. The distant trees look good but there could be some more.
The lines in the water are at tile boundaries.
I really like the lighting on the grass through most angles except perhaps directly towards the sun. I think my new grass surfacing fixes that but I'll have to check that a little closer. The other thing that might be nice is if there was an increased reflectivity directly opposite the sun, but it's pretty good as it is.
Widely distributed grass tiles look a little odd as grass clumps aren't square
Somemore variation in colour of the grass would also be good, but that will be fixed with my new grass model.
Rocks/stones yet to be added.
Blue spruce model looks too crude for close ups.
The reflections on the leaves towards the sun are "intentional" but their appearance is a limitation of using a flat leaf surface. The reflection covers an entire leaf group uniformly.
There are parts of the qtvr that look quite realistic, so there's a lot of potential. I find QTVR is a good test for cloud settings. These look better than i expected
