Having gone through your website this is my observation:
1. You are reading news using pictures. This is like trying to play within the niche of CNN AND BBC with only pictures now this is a hard line to thread. I do trending news but I discuss it and talk about my perspective about it.
2. You are talking about 5-10 topic on each video, why not discuss one trending news using your knowledge and research. People want to know what an ordinary person thinks about the news around them. They want to have a discussion not have someone read news to them unless they are watching news channel. Make it interactive and more personal.
3. Thumbnail: They are the same. Can you make it more attractive and specific to the trending news. When I looked at it I felt that it was the same story as I hardly look at titles anyway.
When i started YouTube last year, I learnt that people come to your channel to know what you think about the news. They need you be interacting with them and not be another news TV channel as this is YouTube. If you like check my website to see what I do with news article in African and my country.
Hope this helps and we are all learning.
