@Jackalhead - lol I knew that would come up, as modern zombies seem to have guts spilling out all over the place, missing jaws etc. I felt that more normal looking zombies that behave aggressively (eg 28 days later, World war Z, even I am legend) are far scarier than gory zombies that amble towards you at snail's pace. They also don't exist, so you can make them look however you want
edit - the screenshot I use at the start of the thread probably doesn't do them justice. Here's a better one.
another edit - if there's a call for it, I could easily add some retextures with more gunk/growths/discoloration on the skin.
