Amazing
Really good, here's some things I liked:
-Smooth animation
-Sound effects(especially the swords)
-Combat choreography(fast-paced but not too chaotic)
-Move interaction(this was just simply cool, good idea)
-Good use of slow-mo(Put em' in just the right places)
My favorite of it though was probably how you could see EXACTLY how they were swinging their swords so you could see some of the cool tricks they do. Most combat stick fight movies go too fast for you to keep track. You kept it going at a good pace but you let it go slow enough so the audience could admire the animation and combat. Really good though, 5/5 10/10!
