You only started in April, so I would worry about just making content for now. To be honest gaming on Youtube is a very tough business. If you didn't start early in the fad then you are looking at a few years of hard work and sleepness nights. I for instance work 14 hours a day on my channel by making content constantly for it.The outcome thus far is just over 3000 subscribers.
Now I am not complaining (I actually love the audience I have right now to death!) but what I am trying to say is that if you don't have the stomach to treat it like a career then I would say back out now while you still can. It takes a lot to be a Youtuber and it takes a lot more to be a successful one.
First you need to make your videos as professional as you can. Don't start videos in the pause screen, people seem to not like that. You also want to start all your videos with you introducing yourself as soon as possible. I noticed you mic check sometimes at the start, which could be edited out if you felt the need.
Another thing is to try and feel engaged on what you are playing. I watched half of your FEAR 2 part 2 video and sometimes you just sound...bored? If you don't have anything to say don't fall into the cracks of explaining what you are doing. The viewer can see what you are doing in the game, so saying "Ok I just picked up this and then I am going to pick up this and now I am going down this corridor" is a big no no when it comes to Let's Plays.
Either way those are a few things to think about. Youtube for the most part is about learning a lot of things yourself and you will learn many of your own do's and dont's along they way. I wish you the best of luck
