Goblin in the Castle Dungeon (Digital Art)

An agile goblin crouches in a damp castle dungeon. Digital art, ultra-detailed, cinematic lighting. Cold stone walls, dripping water, cobwebs, and rusty shackles. The goblin has green skin, pointed ears, sharp teeth, and messy hair. It wears torn leather armor and a hood, gripping a crooked iron key in one hand and a glowing rune-dagger in the other. Amber torchlight spills across the floor, casting long shadows and making the goblin's emerald eyes glow. The atmosphere is tense and subterranean, with moss and grime clinging to walls and metal, rendered in a rich fantasy color palette.
