As WandW posts, the face texture is very basic with a tint to the diffuse_color chip which really shouldn't be there.  That chip should be white (double clicking on the chip will give you the option to change the color).  

The torso view does show a complicated node arrangement, but I don't thing it is a BB creation.  Typically, BB uses Alt_Diffuse as the primary plugin for texture maps; this one does not.  But I do see a blue chip for the Alt_Specular which leads me to believe that this particular arrangement is borrowed from an original V4 mat texture.  

Again, I agree with WandW, an advanced texture set for the face should be located somewhere, perhaps under Materials.
