This is really great! Hmm if I were to change it up editing/style wise I'd keep doing what you're doing with all the information you're giving but maybe crop in on your self so that you are framed properly. A tighter shot while filming would solve this (Remember the rule of thirds!). I'm not sure if you've even seen the youtuber Bill wurtz. This is his video on the history of Japan -
He keeps the energy really high with sound effects and tiny animations which really help convey information. If you have any experience in After Effects you could have the pop up's be more engaging, bill wurtz have a very definite style but with some practice you could develop into a really engaging youtuber. Not that you're not already!
I'd chose some different music too for the background, instantly it feels like stock music.
On a side note, a different background would be nice. The room with curtains is a little dull - You wouldn't happen to have a green screen lying around?? ha
Hope this helps, keep up the good work!
