It's really good, but the voiceover could have been better in places? And I don't really know what happened next? If you made a series out of this, it would probably become one of my favorites. How did you get those weapons to appear then, with that magic circle? When they seperated, that was a good scene. I am an animator and that looks like hardcore effects!
Overall, very good, and you have earned an upvote and should get more views and subs.
