Landscape - Procedural Material

Some of my recent procedural doodles made in Substance Designer. Not sure if the result is good enough but wanted prove how important and meaningful materials are nowadays and how much they can introduce to even simple geometry.
If anyone wants to get this, it is on my gumroad: https://gum.co/ZSwAt

The material in action - applied to a flat tessellated plane and rendered in Marmoset Toolbag 3

Plane 2 Landscape - stages of material apply (none -> adding roughness, normal -> adding color -> adding the heightmap)
