Cyberpunk Brain Graffiti Alley

Create a cinematic photorealistic urban alley mural scene at dusk after rain. The image shows a red brick wall at the end of a narrow alley, covered by a large hyper-detailed 3D graffiti mural of an exposed human brain, with glossy pink folds, dark mechanical seams, tiny circuit-board inserts, and glowing orange lightning cracks radiating outward. Across the center of the brain is bold metallic wildstyle graffiti lettering spelling graffiti_word, with chrome-blue highlights, purple shadows, black outline, and a sharp arrow extending from the final letter. Behind the brain, add layered colorful street tags and abstract spray shapes in blue, yellow, red, and green. Around the mural include exactly 6 visible neon circuit nodes: 3 purple hexagonal nodes on the left and lower left, 2 purple hexagonal nodes on the right and lower right, and 1 small orange node near the upper right, all connected by thin glowing cables and electric lines. The brick wall has realistic grime, rain streaks, old paper scraps, and urban decay; include exactly 4 torn paper poster fragments on the wall, plus a small handwritten tag reading small_wall_tag near the lower left. Add industrial details: a black metal fire escape platform above the mural, horizontal black cables across the upper wall, and a beige electrical junction box at upper right with wires running down. The wet pavement reflects orange, purple, green, and red lights; place exactly 2 discarded drink cans near the bottom left foreground, one upright red can and one crushed can lying on its side, with a few small bits of litter scattered nearby. The alley extends into soft-focus city depth on both sides, with neon storefront signs blurred in the background and exactly 1 distant hooded pedestrian silhouette walking on the right side. Use a moody cyberpunk street-art atmosphere, shallow depth of field, realistic rain reflections, volumetric mist, high contrast, ultra-detailed textures, 16:9 composition, no watermark, no extra readable text besides the specified graffiti word and small wall tag.
