I'm not entirely sure what you're talking about...I see some things that 
could be rendering or JPEG artifacts, but they aren't in the closeup. 
There are rather strong vertical and horizontal lines in the shading, 
one of them vertically splitting the closeup, but it looks like you used 
a noise function to displace the surface, and the Perlin noise used in 
POV produces such artifacts.
