Fantasy Art — Side-by-Side Results
Prompt
"A fantasy art illustration styled like a casual TikTok “morning coffee check-in”: a 20s woman with wavy chestnut hair in a messy bun, wearing an oversized hoodie, bike shorts, and sneakers, holds her phone at arm’s length and looks near the camera with a relaxed half-smile. She’s in a cozy neighborhood café with sunlit windows, but the latte foam swirls into glowing runes while a tiny dragon perches on her shoulder and enchanted ivy creeps around the table; natural phone-camera feel with soft daylight mixed with subtle magical glow. Keep it candid and approachable like an Instagram story selfie, not editorial—slight motion blur, imperfect framing, realistic social-media vibe."
