This was good story content for a flash length story. I didn't feel particularly emotionally connected, nor was I on the edge of my seat with excitement, but the imagery was memorable, the ideas interesting, and the resolution fit the rest of the story, and then it was over before it had time to be too long.
I think I was supposed to feel some fear when the wolves came over the mountain, fear of being attacked by wolves that is. That would be my immediate fear, sure, but after the initial rush I'd be more afraid of starving to death as the wolves picked the landscape clean of anything edible by humans.
