Ok well first of all, one thing you should do is rather then having the Turn Cinematic Mode On and the Fade Out over 0 Seconds trigger on a Elapsed Time is 0 seconds event, you should have it on a Map Initialization event. That way there will not be that pause where its the normal game camera between when the map finishes loading and when the cinematic starts.
For the first one I don't think the music suited the cinematic at all, and a better choice in music would of added to the cinematic a lot more. Also when the huge group of villagers get killed by the main character, you should avoid the thing where its fades out and then fades back in to show them dead. I think you should have it so you can see how they all die.
For Part II it was a lot better then part one, however it has the same problem that the music choice was not very good. The camera work was better then in Part I, however in the battle part at the start against the knights the camera basically just rotates around the battlefield, which you should also try and avoid. Also when the bridge is destroyed, I can't actually see how the bridge gets destroyed, it just collapses on its own. So I would try and show exactly how the bridge gets destroyed.
Also there are several spelling errors throughout the cinematics, I would try and fix as many of those up as possible.
