It was pretty good...
It was far better than I could do anyway, just a few things you could tidy up in it for the real one. All the zombies looked pretty menacing, although (I think the third zombie?) Only had one leg and it was unlikely he'd do anything except for fall over.
Avoid doing things like that, zombies lacking arms and with assorted sharp objects stuck in them add to their "Character" but you can't over do it.
