You speak pretty quickly and as mentioned before, it does seem quite staged and you seem a little uncomfortable at times.
With the fallen sheet, you could have gone more along the lines of having it fall in the middle of a line and say something like, 'scrap what I was going to say - choose a good backdrop' sort of thing. It would have been more... flowing and less blatantly planned.
Obviously topics are important too and any Gary Barlow fans will now avoid your videos or flood your comments with insults and dislikes, especially as a new starter (it doesn't help you used a word which many people aren't fond of to name him).
People will obviously also expect lighting to not be too great for new starters, but natural light will look better than the yellow glow you currently have.
And, as previously mentioned: involve the community. Many YouTubers see themselves as part of a huge community, along with their viewers and subscribers - it'll also get you a few comments too.
