Blender 2.8 My soil shader looks too glossy I'm trying to do a soil material using the following textures:

I applied a 'displaced' modifier and built the shader nodes but my surface looks too bright and glossy


The material in the site looks more rough and appears to have the rocks on the model, but in mine looks like mud. I watched several tutorials and tried to change several values on my node set and I can't get it right.

Here is my node set. Could anyone help me to take off this glossy aspect?
I think you have to set a brighter color to your color ramp, and try playing with the position of the handles. Pure black makes glossy, pure white makes rough.
