Bridge Inside a Lighthouse: Concept Art Vision

A hyper-detailed concept art rendering of a colossal bridge winding inside a towering lighthouse. A glass-walled spiral bridge threads between observation decks and keeper rooms, wrapping the cylindrical stone core. Warm amber lanterns cast long shadows on riveted steel girders, while cool blue safety rails glow along the span. Sea fog pours through porthole windows; a stormy Atlantic churns beyond the lantern-lit interior. The scene blends steampunk and architectural fantasy with moody cinematic lighting, painterly textures, and a high level of detail suitable for ArtStation-quality concept art.
