MMmmmmm…..This is very good. You should draw this out. Kinda a “Skulls” feel. I enjoyed this.

Interesting. I like it quite a bit, and your dialouge is very impressive. But I would have liked a better, well not better, but a stronger word or phrase to use at the end in place of “With a howl, they descended on him.” Maybe try using something with a stronger more violent pull that will interest your readers more. Other than that I have no suggestions, for this was actually a very splendid piece.
