The hill colours are a bit strong, and it could do with some trees, but the terrain is very nicely formed. Procedural or heightmap?

The terrain is build by two alpine shaders, I think thats why the render is so slow.
The colours are procedural (7 colours, 58 nodes):

The colors are all very vibrant.  I would consider using some sort of different color for the grass.  A duller color would work, since at that level you won't see the blades' color so fully.
