I like this. The erosion is great, so are the rocks on the talus slopes, and the trees/shrub seem about 5-10m high to me. A few things though; it seems like the whole terrain is leaning backward, so I would use a smaller FOV. I think you raised the angle to 80ยบ or so? And perhaps the colors of the stone are a bit on the warm side, but I don't know about that kind of terrain. And a few more species of shrub/flowers, or the occasional dead tree may well find a place in this landscape.
