Try not to add too many single kills, try not to make your kills go like 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Add a few more effects, even a faded border would do. But otherwise you had some awesome no scopes head-shots what i could probably never pull of.
but i got a few tips
Cut out un needed no scopes if they're the common kill
7 minutes is kinda long, and i didn't see AS MUCH action as I thought
I'm not the pro at montages, well because I can't record without lag.
If i had a better computer, i'd have like 3+ 10 minute montages already
I like how you cut out the dead time (Un-needed seconds of you running around)
Try to sync the kills with the beat of your music etc; (It's hard, but it makes the montage sexy)
I like some of the sniping, but the rest are kinda
"Noobish" hahaha 7/10, it was too lengthy and had some boring kills
