One of the things I love about gaming is that whatever is going on in your real life doesnt matter, you can sit down and immerse yourself in fantasy and wonderful things.
I advise not to upload raw streams to youtube because tbh not many people are going to watch them through. I advise twitch because it is a lot easier to get new viewers and although they might not all stay its still easier than youtube.
What graphics card do you have? Find out if you have an AMD graphics card or an Nvidia graphics card. AMD graphics card allows you to use the free recording software Raptor and Nvidia allows you to use the free recording software Shadowplay.
I advise you watch The George Show on the freedom youtube channel (https://www.youtube.com/user/mcnfreedom) George mentioned one of the best ways to grow is by collaboration. Go and find yourself another youtuber with similar amount of subs and similar content and ask for a collaboration...
Wait about a week and check your emails everyday. If you still get nothing from freedom fill out a ticket in the support section. As for your channel it looks good man, just make sure to keep everything high quality and keep a regular upload schedule.
Play what you enjoy, people go to listen to the commentary not the gameplay. Look at Pyrocynical for example, recently he's been playing quite an old game with pretty terrible graphics but that's had little to no impact on his videos what-so-ever.

Youtube is over-saturated. It's a fact. And with 5 subscribers I'm afraid you'll be lucky to get 5 in a day. You just gotta make sure you are creating high quality content and work hard at it. Youtube is hard work and results only pay off if you put in the effort. Good luck.
