I’ve also checked your thumbnails for A/B tests of the most recent video:
The thumbnails still lack the appeal to make viewers click on them. The presenter's face is small and appears distant within the image.
We should encourage the presenter to display an emotional expression that reflects the video's content, accompanied by a curiosity-inducing text (2-3 words).
For effective thumbnail references, it's best to showcase a large face against a clear background. For this channel, consider Mr. Beast's channel as an example.
<aside> 💡 I know Mr. Beast is in a different niche, but the main principles are the same. I've even tried them with many educational channels, including my own channel. It’s all about (BIG FACE with a posture reflecting what’s inside the video with a clear background)

We can use these thumbnails as an example for something related to our channel.
