The story looks a little bland to me, though I suppose that's since it's just a premise and doesn't get very far into it. I'd take care when writing it though, as it doesn't seem that involved or original.
Also, your mapping is pretty good, but I'd try to spice it up more, maybe use the elevation/cliffs a bit more, or use a fog for lighting and shadow or something. Compositionally the maps look alright but for some reason they're just not standing out to me.
