Fairy Tale Book Cover: A little girl and a small fox stand in front of a glowing forest cabin. The moon is huge and dreamy, with stardust floating around them, firefly lights illuminate the meadow, small white flowers adorn it delicately, mist creates a soft sense of depth; an ornate bronze fairy-tale border surrounds the entire scene. The color scheme features a contrast between blue-purple and warm gold. The facial features of the characters remain consistent with the original image. The overall style is highly dreamy, gentle, and magical, suitable for a children's picture book cover. | ![]() |

The booth's glass reflects city streetlights with a bokeh effect, creating a vintage film style. | ![]() |
A hand holds four black and white polaroid-style photos of portrait against a blank white background. | ![]() |
