The Subsurface scaling value of 0.03 is good enough, a higher one will cause a glowing effect.  I usually use a value of 0.015 - 0.02.  The Subsurface Color can vary depending on what type of color you want as a scatter.  On the NormalMap node, change the space to Tangent.  What is your Subsurface radius?

Question: Why is your roughness so low?
