Digital painting of a close-up from a high angle above of a young detective girl walking slowly down a wet cobblestone alley at night, looking down at a trail of glowing footprints made of soft blue-green mold that lead into the darkness. She has a short black bob with blunt bangs, large dark eyes with small white highlights, a faint blush and dark lips, and she holds a brass magnifying glass close to the ground, its lens glowing with the light of the mold. She wears a long beige trench coat with the collar turned up, a dark checkered deerstalker cap and a red scarf. Fuzzy mold spots spread across the wet stones, small pale mushrooms sprout between the cobbles, and glowing spores rise around her boots. Rain drips from the brim of her cap. The palette is near-black navy and slate with glowing mint green, beige and one red accent. Sketchy dark lineart with fine hatching, textured grainy brushwork, fuzzy airbrushed mold spots, soft glow on her face from below and a moody mystery atmosphere.
