Good Art! Nice pace.

I like the way of narrative, but the story of Zhao Yun playing music at the open gate of empty (unguarded) city is not exact accurate - It was Zhu Gelian (Zhao's boss, the prime minister) who did it, scared off his arch enemy - Si Mayi.

I guess I miss the background of the plot. The tension and atmosphere are well built. I think you used 3D software right? or I am wrong, because it does not seem to use the full advantage of 3D softs (like parallax , swivel)
in general nice job and have the cinema grip.
