I LOVE the research you put into this. There is a LOT of value in well-scripted videos like this. In my experience they often take some time to start performing in Search... but when they do they are often channel drivers.
You did a lot of things right; you immersed the viewer with multiple visual elements. In particular I like how you decided to throw the image of the Jackson on screen while describing their differences; little things like that go a
long way in the format of visual storytelling and you made some real good decisions.
I am going to be critical of a couple things though. There are some things that could use some improvement. Let's compare your presentation against one that the BBC did...

You are using the approach of talking directly into the camera... there is nothing wrong with this (I use a similar approach for presentation style videos). As a note be mindful that when you do this
you are only talking to a single person. Cater your speech to the individual watching your video. There is no group of subscribers on the couch huddled around their phone. It's one person; treat the viewer as such.
Your style though is a little bland. Though minimal, can you see the difference in the lighting that the BBC is using in their shots? They are setting up lights specifically to shine a light of the bald parts of these guys heads (I am not even kidding). They are seating them in such a way so that the lighted parts of their faces are contrasting against the darker backgrounds. They seated these guys in a way that causes the lines of the windows and angles of the walls to draw the eye towards them as a focal point of the shot. They also Switch up the focus and zoom in on these guys as they are talking. I would highly encourage you to add this knowledge to your presentation.
Watch Nick Nimmin. He does this straight-to-the-camera style presentation. He is bouncing all over the place when he talks. It creates movement and action. You don't need your footage to look like a rave at Club 54... but a little activity in the shot to help keep interest will help video performance. I would suggest zooming in/out of some of your clips to help with this, and I would HIGHLY advise you go to Home Depot/WalMart/Sutherlands and get 2-3 super-cheap can construction lights and some super cheap, low-intensity light bulbs to 'paint your set.' Spend a little time creating a more complex, intriguing visual presentation to add to your solid script work, editing and story-telling. There are a ton of videos out there on beginner lighting tricks that when combined with some simple editing and movement will likely provide a significant upstroke in your overall video performance.
You are skilled and you are talented... might as well bring the set design up to your caliber of video!
