Concept Art — Side-by-Side Results
Prompt
"A 22–28-year-old woman with shoulder-length wavy dark hair in a loose hoodie and bike shorts holds her phone slightly above eye level, glancing toward the front camera mid-sentence like a TikTok “quick coffee run” story. She’s standing in a small neighborhood café by the window with morning sunlight spilling across a chalkboard menu and pastry case, candid messy bun vibes, one hand gripping an iced latte. Render as AAA game/film pre-production concept art with painterly brushstrokes and matte-painting environmental detail, dramatic but still phone-camera framing and natural lighting, authentic UGC feel (not editorial)."
