Alien humanoid creature on white studio background - AI Image Prompt

3D rendered full-body shot of a terrifying alien humanoid monster against a plain white background

Subject: emaciated female-form creature with pale green-grey skin texture resembling dry, cracked earth and exposed muscle fibers, glowing yellow eyes, jagged teeth in sunken face, spiky shoulder blades protruding from the back. 

Action: crouched on all fours but standing upright enough to show torso and limbs clearly, hands clawed forward menacingly, long taloned fingers gripping air, feet planted with sharp claws digging into invisible ground. 

Environment: completely isolated white studio backdrop with soft shadow beneath subject for grounding. 

Lighting: even bright frontal lighting that highlights every texture of skin wrinkles, scars, mucus-like sheen with subtle shadows under limbs and torso to define form without harshness. 

Style Details: hyper-realistic digital sculpting style combining anatomical horror with biomechanical grotesquerie; detailed subsurface scattering on skin suggesting moisture or decay; cinematic character design typical of high-end VFX concept art or monster movie stills.
