Yes, it really helped bring out the details around the mouth.  PP focal
blur was used as well.  Here's the global_settings:

global_settings{
ini_option "+QR"
  post_process{ focal_blur{ 100, 30, 4, 1} }
  radiosity{recursion_limit 5 brightness .8 gray_threshold 0.5 normal
on}
}

I had to raise the gray_threshold to keep everything from looking blue.
It also increased the warmer colors on the shadowed side of the tiger.
