A Victorian-era detective riding a steam-powered hoverboard through the bustling streets of a futuristic London, gaslamps casting a warm glow on the cobblestone, while holographic Big Ben looms in the background, decked with cybernetic gargoyles. In the sky, an airship mapped with constellations floats, and a crimson sunset blends with neon graffiti that seemingly interacts with the vintage fashion of street-goers. The detective, with a magnifying glass outfitted with digital interfaces, examines a robotic raven perched on his shoulder, encapsulating the fusion of Sherlock Holmes intrigue, steampunk aesthetics, and visionary technology.
