Fantasy Art — Side-by-Side Results
Prompt
"Fantasy art illustration of a 20s woman with long wavy brown hair in a cozy oversized hoodie and bike shorts, holding her phone at arm’s length for a casual selfie and looking near the camera with an easy, candid expression. She’s in a small neighborhood café, but it’s an enchanted tavern: floating rune-lit latte art, a tiny dragon perched on her shoulder, and a cloaked elf barista behind her, with warm morning window light mixed with subtle magical glow effects. Authentic Instagram-story vibe, slightly imperfect framing, natural lighting feel (no studio look), everyday moment turned epic."
