Fantasy Art — Side-by-Side Results
Prompt
"A fantasy art illustration of a mid-20s woman with long wavy dark hair in a cozy oversized hoodie and leggings, holding a phone at arm’s length for a casual selfie while looking near the camera with a relaxed half-smile. She’s in a real-world coffee shop, but the background subtly shifts into an enchanted tavern—glowing runes in the latte foam, a tiny dragon perched on the pastry case, and soft magical light spilling from stained-glass windows mixed with natural morning window light. Candid, Instagram-story vibe with slight motion blur from her hand, messy table details (keys, lip balm), and realistic phone-camera perspective."
