Fractal Dimensions

We are fractal beings and doing fractal things are natural for us.
A sculptor refining a surface, can achieve in one minute what could
take computer a day to compute. 

Is there a difference between a fractal dimension, and “human
imperfection” when creating jewelry? What distinguishes the
acceptable fractal dimensions from other imperfections of a man made
object; or is imperfection just a poorly executed fractal dimension?
