re: very realistic
Although it really does look real, it has a few rough edges.
1.) It needs a darker area. Perhaps in a place with only 2 sources of dim light.
2.) The zombies are too less zombie like. Notice the blood in my Domo-Kun is hungry picture at my page. It has blood coming out from the eyes and mouth. So... yes the zombies should be more like that.
Other then that this is great and I like it.
