Your commentary! You keep the talk going and entertaining. Then it really doesn`t matter if you are good at the game or not. I also like that you keep the channel intro short and to the point. If this is your first shot at youtube you are off to a good start in my opinion
What you should consider to change or do different:
Try to remove the black bars on your vids. People tend to get annoyed by them. Google what settings you need to use according to what type of editing software you have.
I would also recommened not to record the channel intro when it`s night time in minecraft. Many people watch on their phones and then they just see a black screen with your voice over it.
You should also consider getting a better mic in the future, but it works for now.
