Fantasy Art — Side-by-Side Results
Prompt
"A fantasy art illustration of a 20s influencer with long wavy brown hair in a casual oversized hoodie and bike shorts, holding a phone at arm’s length for a slightly messy selfie while looking near the camera with a relaxed, candid expression. She’s in a cozy modern café, but it’s subtly enchanted—tiny glowing runes swirl from her takeaway coffee, a small dragon the size of a cat naps on the table, and a distant armored knight waits in line behind her. Natural window light mixes with soft magical glow effects, like an Instagram story snapshot rather than a polished editorial."
