there is no random rotation of the tree blocks 6-3-1, 6-3-2 and 6-3-3:



So the result looks like a plantation or nursery garden ("pépinière" in French) and less natural.
And there is no tree block like in Canyon that could be placed on the sides of the hill (Terraforming type 2).
I had the hope that the "overlay" (Terraforming type 6) would make it, but it works only on flat ground or flat top of hills/mountains.
