Inside a shadow-dusted cavern behind a thundering waterfall, a Tengu with glossy black plumage and a bright red beak sits at a carved stone desk, composing a symphony. Torchlight flickers along copper sconces, casting amber pools on damp basalt and scattering jittering reflections across a shallow pool carved by underground currents. A parchment score unfurls, inked with coppery notes; a feather quill hovers above delicate staff lines, while a tuning fork and a small ebony violin rest within reach. The Tengu’s robe, midnight satin threaded with brass filigree, catches the glow as his obsidian eyes lock on the page, then lift to gesture with a feathered baton toward the unseen choir of shadows. Mist from the waterfall threads through stalactites, mist-sprayed moss glistens on the rock, and crystal droplets bead on rough-hewn ledges. The cinematic wide-angle composition sweeps from the raw foreground rocks to the focused figure and the vast, echoing chamber behind the veil of water

The image shows a black and white illustration of a man sitting in a cave, holding a guitar and writing on a piece of paper. He is surrounded by rocks and there is a body of water in the background.
