Thumbnail

There are various aspects of a thumbnail that you should be aware of: 
 Check if the people present in the video are easy to see in the thumbnail. Check if the text on the thumbnail is readable if scaled to YouTube size. You can use figma for this. Consider the “appropriateness” of the thumbnail to the content of the video. The artist should have watched the video to understand what is appropriate. If artists have internally reviewed already, skip thumbnail checking.
