Character Design — Side-by-Side Results
Prompt
"A candid phone-camera selfie of an original influencer character (mid-20s, warm brown skin, big round glasses, asymmetrical curly bob with a teal streak, small star-shaped birthmark under one eye) looking slightly off-lens like she’s mid-sentence, doing a casual “outfit check” in a bedroom mirror. Distinctive character-design silhouette with stylized proportions (slightly oversized hoodie sleeves, chunky sneakers, high-waisted cargo skirt), detailed costume accents (enamel pins, layered necklaces, tote bag with bold patch icons), shown in a turnaround-ready stance with one knee bent and phone raised. Natural morning window light, messy-real room details (laundry basket, skincare on dresser, poster wall), authentic TikTok/IG story vibe with subtle motion blur and imperfect framing."
