Character Design — Side-by-Side Results
Prompt
"A candid phone-camera selfie of an original influencer character (early 20s), warm brown skin with freckles, big round glasses, long honey-blonde braids in a high ponytail, wearing an oversized mint hoodie layered over biker shorts and chunky white sneakers; she’s mid-step doing an “outfit check” while glancing near the camera with a relaxed half-smile. Real coffee shop setting with visible menu board and pastry case behind her, one hand holding an iced latte and the other holding the phone slightly above eye level, natural window light + soft indoor ambient lighting. Character-design emphasis: distinctive silhouette (braid-ponytail arc + oversized hoodie), stylized proportions (slightly larger head/eyes), detailed accessories (phone charm lanyard, enamel pins on hoodie, tote bag with bold patch), turnaround-ready pose that reads clearly like a TikTok thumbnail."
