I guess it also took me a while to respond, eh? Well I like what I'm seeing there, I was actually going to be writing a fic similar to this at some point, I mean the tone, that is. It was to take place after a long and drawn out nuclear war where, when people finally emerge, they discover that the creatures they believed would be outside had mutated. I may get around to writing it someday, but I don't really have the motivation...
I hope to see you post a second chapter sometime soon.
