15. Add a Mix Shader node and a Glossy BSDF shader, and connect them to be mixed
with the Diffuse BSDF shader. Set the Glossy BSDF node's Roughness value to
0.150 and the Mix Shader node's Fac value to 0.300 . Connect the Normal output
of the Bump node to the Normal input socket of the Glossy BSDF shader, as shown
in this screenshot:

16. Add an RGB node (press Shift + A and navigate to Input | RGB) and a MixRGB node
(press Shift + A and navigate to Color | MixRGB). Connect both the Color outputs
of the RGB and Image Texture nodes to the Color1 and Color2 input sockets of the
MixRGB node. Connect the Color output of the MixRGB node to the Color input
sockets of the Diffuse BSDF and Glossy BSDF shaders.
