Pool horror: woman's expression turns to terror with crocodile AI Image Prompt

Local repaint and modification of video footage: Change the expression of the woman lying on a pool float from happy to extreme fear and panic. Her eyes should widen in shock, her mouth open in a screaming motion, and facial muscles show tension. Simultaneously, add a crocodile swimming slowly toward the woman, its body partially submerged, with back and eyes visible, creating realistic ripples and splashes. The woman's body posture, pool float, background environment, and camera movement must remain 100% unchanged. The final effect should evoke a tense, terrifying atmosphere, and the crocodile must integrate with the water in a physically and optically consistent way.
