Thumbnail Review

Why It Doesn't Work

• The thumbnail shows afternoon tea, but the title is about London's history, causing confusion.
• The image is cluttered with too many small food items, making it hard to see.
• The background is busy and uninteresting, distracting from the main subject.
• There is no text on the thumbnail to clarify the video's topic.
• The thumbnail lacks any intrigue or excitement to encourage clicks.
