I think the music needs to be toned down a bit because it can be distracting. The rewind feature can be helpful to show the subtle little strategies in places. The most important thing you'll want to add are text bubbles, arrows and such to bring the viewers attention to PC and mob placement and such.

Think of it more like a football instant replay than an EQ music video.
All in all it's a pretty good first trial at just making a video in general and playing with effects. I can tell these will turn out pretty good.
