My new Halo youtube channel

Hi!
I have just made my own halo youtube channel, and i would really appriciate if you took a look at it, and gave som feedback. I just uploaded my first video, a montage. I know it is not the best, but it is my first ever time making a montage! Constructive critisism is greatly appriciated!
