In general the video in my opinion is okey. But deffinitly not good yet. There is a lot you can change and or improve on.
The intro and menu showcase is 51 seconds. The total time of Intro and Menu showcase should not exceed 30 seconds.
50% of the sniper shots are missed... You can do better than thatPlay a game more and cut two games for the clips but then more interessting clips. In general i would like to see clips with more kills.
