Here's a side to side comparison for my Quentin texture, left with original settings and my Quentin lights, one AO light with AO set to 0.4. Right is with VSS, but with major changings for the maps, bump amount reset to -0.1, displacement for the face reset to 0.2, added some translucence to the eyewhites and irises because I raised the AO to 0.7.
