Transformación zombi en primer plano

[Start with a close-up of a woman's face, her expression calm and natural. Gradually, her skin begins to pale and take on a grayish, decayed tone. Dark circles form under her eyes, her cheekbones become more pronounced, and veins start to appear, creeping along her skin. Her eyes grow clouded and lifeless, while her lips crack and peel. Her teeth slowly become jagged and yellowed, and parts of her skin begin to tear away, revealing rotting flesh beneath. By the end, she's fully transformed into a decayed, terrifying zombie.]
