jy76tn, there are basic problems with your node arrangement.  Reflection_Lite_Mult is checked on; no need for this to be active unless the surface will intended to be shiny or reflective.

The blender node is plugged into a Specular_Color which appears black; a black color chip or a value of 0 means no effect on the final render outcome.  In this case, it is a wasted node connection.

Also, the blender node is connected to a non-active Transparency.  Again, a wasted node connection of no value.

 Texture Filtering set to quality will degrade the resolution of the image if you are interested in rendering closeups.  I prefer filtering to none.

I would say Winterclaw's post is more correctly setup and in keeping with lesbentley's link.
