At the beginning of the video, you might want to speed it up a bit starting from the Title up to the part where the kids are shown... all in all, i would like to commend you in doing a great job... an the violence? not that much... yeah, the narrators cannot seem to find a perfect term, but hey, narrating is different from the video editin part... narrating is just done after the whole thing has been created.
looking forward to your next clip...
