Prompt
A candid street photo of three friends casually posing in coordinated black and gray techwear outfits with layered street style, harnesses, and utility accessories, standing relaxed in a narrow urban alley. Behind them, a large, detailed graffiti mural of an octopus dominates the doorway, its eyes replaced by vintage TV heads; the octopus's tentacles twist and dissolve into glitch-like brushstrokes extending along the brick walls. The alley’s surfaces are heavily textured with peeling paint, faded posters, and layered graffiti tags. Natural daylight filters softly into the confined space, casting subtle shadows and highlighting the rough urban textures. The composition uses a slightly tilted, eye-level framing, capturing an authentic spontaneous moment typical of candid iPhone photography with genuine street ambiance, rich graffiti detail, and realistic tactile surfaces.
