Ultra photorealistic live-action film still captured on ARRI Alexa 65, 50mm f/1.4 anamorphic lens, hyper-detailed textures, insane realistic skin pores, freckles, sweat droplets, subsurface scattering, micro-imperfections, 16K raw photo, no animation, no CGI artifacts, lifelike human captured in real moment, sharp focus, cinematic depth of field. A girl's face and appearance match 100% to the reference photo. She is a Commonwealth black-ops seductress, in skin-tight charcoal tactical catsuit with crimson CRM insignia, crouched behind overturned school bus while walkers claw at rusted metal, blood-smeared machete drawn, ultra-realistic walker finger-streaks on paint, micro-droplets of walker ichor on sleeve and rotting teeth glinting in overcast light.
