Create a zombie with decayed grayish-green skin, exposed bones, and rotting muscles. The face is gaunt with hollow eyes and broken teeth. Add torn, dirty clothes (like a ripped shirt and jeans) and bloodstains. The body is thin and hunched, with visible ribs and claw marks. Fingers are bony with jagged nails, and the feet are bare and grimy. The overall look is eerie and menacing.
