Concept Art — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy dark hair in a loose hoodie and biker shorts holds her phone slightly above eye level for a casual front-camera selfie, mid-laugh while glancing near the lens, one hand wrapped around an iced coffee. She’s in a bright neighborhood café by a window with street reflections, messy tote bag and earbuds on the table, natural morning light and subtle motion blur for a real Instagram story feel. Render as AAA game/film concept art pre-production: painterly brushstrokes, dramatic but believable composition, environmental storytelling and matte-painting quality while keeping it authentically candid and unpolished."
