So the slash light also takes away any Racoon mask shadow effect in the eye socket area and adds the eye light! Your example seems subtle and very nice work. I couldn't see it being anymore pronounced unless it was to be a stylistic effect, I'll check out those references you provided. A deodolight seems pretty powerful, you must of brought it way down, scrims, diffusion, dimmers, etc.
Do you use dimmers? they warm the color as the intensity goes down, would you you ever compensate with say a 1/4 CTB gel to bring the color temp up?
