The channel is lacking mostly any kind of content to really give proper feedback on it. I would maybe recommend doing half a series of a game before really asking for any kind of review.
Your Call of Duty videos are kind of in the right direction. The idea of viewers helping you improve is a nice idea but the commentary is a little unguided. It ends up becoming more like a Vlog and it starts to droll on and on. You stutter and mumble quite a bit too. Try your best not to go "Uuuummm...uuuummm". "Um" is the sign of someone not knowing from the get-go what to say. The commentary seems to go round in circles quite a bit too, which goes with the drolling. You just don't seem to go into your videos with a game plan.
Again try not to mumble because the commentary doesn't become ear catching. Your excessive use of language is rather unsettling as well. I believe at certain points you said the word "F***" in succession three times. It can turn people off. If you want yourself to be seen in that kind of light for some reason then sure good for you but I personally say refrain from it if you want to do it professionally. Maybe it is just how you were brought up in your area as I am from the UK too and I know certain areas of our country consist of this rather rough and tumble use of vocabulary, slang, etc.
Once again when doing videos make sure you know what you are going to be talking about. Maybe write a few little notes to look at when talking to remind yourself what to say when staying on topic.
Hold back from all this "I do wha I wanna do because I'm a boss" and "Yeah I got propa bum raped". Just don't even say that last one in the future as you will be very looked down upon. Youtubers at times are seen as role models and that isn't what a role model should be saying.
FYI your Outcast video just seemed like a stream of mumbles. As I said try your best to speak clearly, especially about your observations.
