YouTube Thumbnail — Side-by-Side Results
Prompt
"Close-up YouTube thumbnail-style selfie of a 20s influencer with shoulder-length wavy brown hair in a messy bun, wearing an oversized pastel hoodie and no-makeup makeup, eyes wide and mouth open in a shocked/excited expression while holding an iced coffee up to the camera. Candid handheld phone-camera angle in a bright, real café by a window with natural daylight, bold colorful menu board blurred behind them, high-contrast lighting and dynamic composition like a TikTok “I found the BEST drink” moment."
