Nope, no cloud nodes are used at all.
And no overlay either. We are Blending, not overlaying.

From the Diffuse texture, we go to a HSV node to control the Hue, Saturation and Value of the skin color. (If required) => (Here you can change the Skin Tone)

From that HSV node output, we create a B&W map in the Math_Functions to feed the Blender node that controls the Displacement.
This Blender mixes a slight Turbulence (set at 0.2 for X,Y,and Z) at a value of only 0.1 with the B&W map to create the skin Displacement set at 0.03
Feeding the Diffuse texture to Displacement this way gets you more displacement in dark area's like brows hairs, and less displacement on lighter area's.

This is augmented by the same minor Turbulence in Bump node and works +/- the same Skin imperfections as other skin procedural solutions do.

The same, but inverted trick, is used for the Alternate Specualr.
Alternate Specular is also connected to a Blender that gets its imputs from the Blinn and the Ks_microfacet (also controlled by the diffuse texture) to add some blue to the yellow skin. => Here the diffuse texture removes the Blue from the Dark area's. No Blue on the brows !

The Blinn is fed by the Diffuse texture and the small Turbulence.

Feeding the Blinn node this way, you get less specular on dark area's like the brows that do not need all that specular, and more specular on the lighter area's that do need it.
There are lots of variations possible here. 

The trick is to use the Diffuse color values to control Displacement and Specular.

=> Dark area's like brows, get MORE Displacement and LESS specular.
=> Light area's like the skin on the belly, get less Displacement but more Specular.
=> The lot "disturbed" a bit by the small Turbulense to create the Skin imperfections.

have a nice day all, and happy Posering, Tony
