I'm by no means an expert when it comes to montages, but it was pretty good. I'm not a fan of 50 Cent and thought the song didn't fit the video very well, and a few clips didn't look like they belonged and the transition from clips could have been better but that's really more on the editing side of things. But the quality was rather good, some very nice no scopes and a sweet killtac on Midship. No easy task in a 4v4 game, for me at least.
Really good for your first montage. Congrats.
