Close up of face and shaders

I ended up just using a Normal Map for the Lizard, but I did take my Displacement Map into photoshop and used it as a paint layer on top of my other colour layers to give more depth to the scales.  It worked out really nicely and I'll probably do this again in the future.

I also used a misss fast skin shader plugged into an mia material x shader to get the depth in the skin as well as the shiny wet look.
