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.

Grok Imagine Strengths

  • Strong creative compositions that help thumbnails feel dynamic and story-driven (poses, angles, and scene energy)
  • Photorealistic, high-detail outputs that can make faces, products, and environments look premium and clickable
  • Cost-efficient iteration at 4 credits per image—useful for exploring multiple thumbnail concepts quickly
