Nice video!
Just a little piece of advice:
When you switch point of view to a 2nd camera, try to keep the same audio track (usually from main, or better sounding camera) instead of having several audio tracks. It can get a little distracting when there's two or more audio with different loudness. I suppose it can be a bit tricky to sync two video tracks to a single audio, but it sure helps the immersion in my opinion.
It's a cool video nonetheless, and it's always fun to see people from around the world playing airsoft
