Russell,
Like all of your work I really like this one. Don't know how I missed it earlier; I agree with your choice of #2, it has a feeling of height and movement about it. I believe the more definition in the clouds adds to the "depth" of the scene if that makes sense.
"Hunting Party is very appropriate; they look all business and mean, not unlike a school of sharks. Awesome mood you've created here.
Cheers, and Thanks for sharing this.
Lance
