Theory of Micro Normal
In order to describe the bumpiness one the surface of an object, there will be a Normal or Grayscale texture in the Bump channel of the Material.

When having the close-up shot for the object, the Normal effect is insufficient to describe the bumpiness and fine lines on the surface.
Note:
For the optimized appearance, only the Head material has additional Normal Blend texture to increase details for certain area on the face.
By overlapping the tiled Micro Normal texture to the original Normal texture, the body can possess fine lines of the skin.
