Prompt
"Close-up phone-camera YouTube thumbnail of a 20s influencer with shoulder-length wavy brown hair in a bright oversized hoodie, holding an iced coffee up to the lens with wide eyes and an open-mouth “OMG” expression, looking right at the camera. Shot in a real coffee shop by a front window with natural daylight, bold colorful signage and blurred people behind them, high-contrast lighting and dynamic composition like a spontaneous Instagram Story screenshot. Saturated colors, sharp face focus, casual candid vibe (slightly messy hair, imperfect framing) like a TikTok thumbnail."

Z-Image Turbo Strengths
