Some nice tactics, good call on getting your guys to back off down the stairs to avoid the grenades, and backing off into the room after baiting them into wasting their frags was a nice move too, I was surprised I didn't hear any cheat calling going off after that sneaky manoeuvre
For future reference I'd always suggest trying to work with open doors when you're the ones assaulting a position, otherwise your enemy can sight up on the door as it's closed, and as soon as they see it move they've got the upper hand - they know where you're going to be, they're letting you make the first mistake.
So doors open as soon as you've established contact, get everyone out of line with the door, and get it locked open as soon as possible. Then you're on even footing, you can peak your head without giving them any knowledge of when it's going to happen, then you can work towards you being the one to get your guns raised and trained on the position they're in, instead of the other way around.
As moose said, some text or commentary wouldn't go amiss with this sort of video, the title made it sound like it was going to be a tutorial, but there's nothing about it that's teaching people. It shows off some good stuff, but unless you already know it, it's not going to be obvious to newer players what you're trying to show.
Baby steps though, it's all about trial and error with your initial videos, sooner or later you'll develop a following that will watch your content without you having to try and tailor it, so really it's just a case of tidying up what you're doing and making everything as clear cut and to the point as possible.
