I would side with DV, but it all depends on how you develop it. If it ends up as a dualistic "good vs. evil" kind of thing, it's not so sweet. But you leave a little wiggle room with your last "Almost." I would have to see how you develop it...
It's hard for me to make the connection with "It's the end of the world" and "There are furries now". So there's no humans left?
You jogged my memory, so I can't help thinking of that Sonic the Hedgehog series which involved the characters in an actual woodland society and such, with the Evil Dr. Robotnik living in the city. If you don't want me to make those associations, avoid bringing up Sonic.
So, give me a character or two, and I would be better able to judge this story. General overlays like this are usually a kind of slow start to a story.
I hope to see what you post next!
