Thumbnail Review

Why It Doesn't Work

• The text is too small and cluttered to be readable on mobile screens.
• The thumbnail text simply repeats the video title, offering no new information or hook.
• The doctor's face is obscured by a mask, reducing personal connection and impact.
• The composition is split and unbalanced, lacking a clear, singular focal point.
• The image lacks any intrigue, shock value, or emotional hook to drive clicks.
