Zombie story -
Interesting idea to have the zombies point of view and how they feel about humans killing them. I like George and the other female charactre (I can't remember her name) it's go a good sense of humor and I would like to read more and see how it turns out.
Riot -
I'm not sure if you are planing to write more but for what you've written I like the descriptions used and the situation. Over all I really liked it and think that you should add more to give the situaton a context.
