Whoa, that's a lot of models to pose! Good job.
The scene looks good, but would have been much more dramatic if you had brought the camera way down around the horse's knee level so we were looking up at this gallant band of heroes. On the other hand maybe that's not what you were going for here.
Looks like this series is going to have some epic high drama, I'm interested to see where you'll go with the story.
