Fortress in a Music Box: Concept Art

A colossal fortress perched on jagged cliffs, carved from obsidian and gilded bronze, inside the inner workings of an antique music box. Ultra-detailed concept art: a fantasy-steampunk fusion with ornate gears and delicate cogs turning beneath a glass lid. The fortress features soaring towers, crenellated battlements, a crystal moat, and wind-swept banners. Warm, amber lighting from hidden lamps illuminates mossy stone, arched gateways, ornate filigree, and gargoyles. The scene is viewed in a cinematic wide shot from slightly above, with the brass frame of the music box forming a decorative border. The tune of the box hums in the air as if the fortress itself is alive. Color palette: deep midnight blues, gunmetal, gold accents, and emerald greens; moody, ethereal atmosphere with light fog and gentle steam, subtle lens flares. Style: cinematic concept art, hyper-detailed, painterly textures, digital painting.
