CONSTRUCTIVE CRITICISM: Well seeing as that this is your first edit, good job but you were way to "out there" you were trying to do to many things trying to make certain shots look cool that it just kind of made it look stupid. Personally what attracts me into videos like this are the intros to the video not the intro of who ever has uploaded this.Also the quality and the pure raw-ness of the editing.
The editing itself was on point, but the footage was just average at best. There were only three or four kills max where I found myself saying "wow!" or "nice!".
I say if you're going for sniper kills and whatnot... whether they're quickscopes or no-scopes, they have to be headshots more often than not or they just don't do anything for me.
