Well no offense, but he's kind of right. xD I mean yeah, they're kill montages but they're not all that interesting. Skill shots, multi-kills and nice long kill streaks are a bit more fun to watch, especially if you have them synced with the music instead of having it just as a background thing.
Again, not saying this to offend you. Just offering some constructive criticism.
I assume you posted the videos for people to watch, so what exactly were you expecting? Only compliments? The attitude is unnecessary.
No attitude meant so I do apologize if I came off crude, just tossed the videos up with no expectation; I know they're not trick shots [which I've got no clue about] just figured someone might find them slightly entertaining if just only a little bit.
