Thumbnail Review

Why It Doesn't Work

• The thumbnail is a vertical video frame with large black bars, wasting valuable screen space.
• The main subject is too small and lacks a clear, engaging expression.
• The text 'cambiar la vida' is tiny and unreadable on mobile devices.
• The thumbnail lacks visual contrast and appears dark and unappealing.
• The composition is cluttered with unnecessary elements like the microphone and tablet.
• The thumbnail fails to create intrigue or curiosity about the video's content.
