Character Design — Side-by-Side Results
Prompt
"A casual phone-camera selfie of an original influencer character design: a 20s woman with a sharp bob haircut dyed teal at the tips, freckled cheeks, and chunky round glasses, wearing an oversized cream hoodie, pleated tennis skirt, and mismatched high-top sneakers with a small enamel-pin collection on the drawstring. She’s half-turned toward the camera in a relaxed “outfit check” pose, one hand holding an iced coffee and the other adjusting her tote bag strap, looking just past the lens with an easy, candid expression; show a clear, turnaround-ready silhouette with distinctive proportions (slightly oversized hoodie sleeves, compact torso, long legs) and readable costume details. Real café setting by a window with natural morning light, visible street reflections and a messy tabletop (lip balm, earbuds, pastry bag), Instagram-story vibe—unpolished, everyday, approachable."
