A reviewer may dislike a color while still understanding the thumbnail perfectly. Another may love the image but misunderstand the video. Separating these reactions makes revisions more useful.
Ask two different questions
First ask what the image communicates. Then ask about visual preferences. Record the answers separately. A correct description of the video's task is evidence of clarity; a favorite shade is a preference unless it affects readability or brand consistency.
Prioritize consequential issues
Fix wrong claims, unreadable labels, and hidden subjects before polishing decorative details. If preferences conflict, return to the audience, the series style, and the practical constraints rather than collecting more opinions indefinitely.
Make a clear decision
Write a short reason for the chosen version. For example, the larger product view identifies the model more reliably while preserving the series layout. This gives future editors a usable principle without pretending that one person's taste establishes a universal design rule.
