Hi,
the grass turns out very well - also I like the dry-ish color of the grass.
The rocks are looking good, too. Nice displacements, not overdone.
But I am wondering whether this scene is under a cloud shadow? The image cold benefit from a few highlights on the leaves or the grass, and the rocks. So I'm missing the lighting dynamics. I think if you can get this in, it will be a win for the image.
How long does this image render?
Regards,
Frank
