Honestly making original content when you're already doing a pretty common thing (making minecraft videos) is very difficult. The only reason the famous video game commentators are famous is because they got into it when it was still new. They were some of the first out there and a riding the wave of success created by a popular game. If you really want to "make it big" maybe consider finding a game that is less known but has potential to be great. Also, as others have said, the quality of the video is kinda bad as in make it less pixel-y. You kinda seem to be more into it for the popularity rather than just having fun posting with friends. Most of the people who are popular now started out making videos with friends as a joke and uploading it to youtube as a secondary. Now it seems people make videos with the man purpose being to put onto youtube rather than recording a good time with buddies. I'm really not trying to be mean, so sorry if it comes off as harsh, good luck I guess
Also, PS don't start that madness with any Army of sorts. Thats overused and stupid and only unites trolls to go out and flame other YTers
