Underground City Artist in Bold Comic Style

An artist in a cluttered studio carved into a cavernous underground city, perched on a metal catwalk above winding tunnels. Illustrated in bold comic-book style with thick black ink lines, dramatic perspective, and classic halftone shading. The artist sits at a glowing drafting tablet, sketching the vast metropolis below while paint splatters and ink bottles clutter the workbench. Surroundings include exposed pipes, cables, stalactites, and steam vents. The subterranean city below glows with neon signs, bioluminescent fungi, and suspended walkways, with distant crowds weaving through the streets. Lighting is high-contrast chiaroscuro, with electric blues, purples, teals, and warm amber highlights. The mood is adventurous noir-fantasy, as if shaping a graphic novel world from within the earth.
