The first page I already find quite cheesy IMO. It's the same zombies as I see every time, but maybe there will be thrills and laughs later on in the story?

Also, make sure you clean up the cart-load of grammar errors and make a habit to use proper grammar 24 / 7; it builds up pretty quickly if you don't write comprehensibly for the first time. A lot of potentially good stories got crapped on because the writers didn't bother to fix any mistakes.
