Why are you using such a low error_bound?  You could easily get away with 10
times that, probably more.  Is that the value you came up with through tuning?

Having a higher error_bound would significantly cut the render time and the
required number of samples without a reduction in quality.  You might actually
have fewer visible artifacts, because the number of required samples for
smoother lighting would be below 1600.

Too bad it uses media, because MCPov is always neat for these kinds of things.
