Character Design — Side-by-Side Results
Prompt
"A candid phone-camera selfie of an original influencer character design: a 20s woman with a sharp asymmetrical bob (black with a teal streak), warm freckles, and chunky round glasses, wearing an oversized oatmeal hoodie layered over a pleated tennis skirt, mismatched socks, and bold high-top sneakers with custom patches; her silhouette is clear and turnaround-ready with distinctive accessories (mini crossbody bag, enamel pins, scrunchie stack). She’s leaning on a small café window counter, holding an iced latte in one hand and her phone in the other, looking just off-lens like she’s mid-story talking, with a casual half-smile and relaxed posture. Real coffee shop setting with visible pastry case blur and street reflections, natural morning window light, slight handheld framing like an Instagram story screenshot (not polished, not cinematic)."

It’s a strong fit for final hero renders of original characters and game characters where detail clarity matters.
Choose Seedream 4.5 when your workflow is iteration-heavy and edit-driven—refining a mascot’s face, adjusting costume shapes, swapping palettes, or evolving a game character across multiple versions.
