Cool! I was like "Is that Tifa?" Smooth polished look to the visuals (graphics & animation). Very nice sound effects. Nice flow with the animation and visual effects/lighting/glow.
It would be cool to see some voice acting here, but the lengthy run-time of the video makes up for it. Gonna be honest, didn't watch all of it. I felt the movie could be broken up into a few different parts, which would be beneficial to you and your viewers. However, it's probably extremely satisfying to publish a good quality 30-min animation.
