Ah, once again a cinematic that's not a total beginner's work!
Nearly everything else was well done but the worst thing was the camera positioning. It was somehow boring and especially in the action scenes much too slow. Damn it, you use the cinematic system to time your cin exactly at short time periods, so don't wait always some seconds before you move again. The fight was technically quite good, but it would have been much better if everything would have been done at double speed.
Besides the cutting speed, you also should try to keep the perspective at a lower level. It's still too much normal warcraft view, from above all characters and with quite much distance to them. Get the camera closer to the characters and also the watcher will get closer into the story!
Well the rest is quite good I think, so I just make some rating:
Terrain 4.5/5
Music/Sound 4/5 (the music also isn't that good I think, sound alone gets 4.5/5)
VFX 5/5
Camera 3/5
Story 4/5 (until now)

Total 4,2
