Manipulated Sunlight. Main light is sun diffused with 4x4' Chimera scrim, side/separation light from silver-gold California Sunbounce reflector behind model. The diffused soft light gives a studio-quality main light and the spectral light from the reflector gives a nice edge to the lighting on the shadow side.
Nice drop off of focus from the Zeiss Otus 85mm without losing detail in the sharp focus area down to the eyelash.
