Nice. is that your voice? If so, thats a great start.
1) Thumbnails....make them more attractive. The thumbnails you have don't really convey enough message about what your content says. I wouldn't click on your video if I saw it on youtube simply because the title is not really grabbing and the thumbnail isn't up to par either.
Tips to help you create nice and grabbing thumbnail, you can search youtube tuts about making great thumbnails.
2) Title of course. That;s the first thing people look at alongside seeing your thumbnail. You want to think of a title that will make people click on the video. Not saying use a clickbait title, but use one that will grab attention. The coronavirus: a short film isnt really a film is it? (a title like 'Coronavirus: why you should not worry/or panic' or Coronavirus: 'the real truth behind the deadly virus' could be more suitable and more grabbing) And the other title doesn't tell me anything about your 10mins video. If you want to remain mysterious with your title, you have to convey the video message in your thumbnail.
Also you started your video on coronavirus with edited news footages. You can get a nice intro for your channel. maybe say something catchy in the beginning, introducing people to your channel and a 10 seconds of 'what they will get to see in the video' which is called 'the hook' before you begin to show the videos. In between each news footage, say something to reflect on what was said in the news. This is what we call 'criticism' or 'review'
There is so much you can learn from other people on youtube who have a large fan base. Don't copy them but take from what they are doing and how they are doing it, incorporate it into your own video in your own unique way.
Overall you have a great potential to be big. Steadily. dont worry if you dont get too many views at first. You'll get there. Keep putting out quality contents. And definitely work on thumbnails and title. They can make or break your channel.
Goodluck
