A spooky gothic castle perched on a rocky cliff overlooking a stormy sea under a massive, cracked blood-red moon. The castle is illuminated by eerie green and blue lights, with numerous translucent, glowing green and blue ghosts floating around and within its arches. Dark, heavy clouds and lightning streak across the sky. A gnarled, ancient tree clings to the cliffside in the foreground, and a haunted graveyard with old gravestones and crosses is visible in the bottom right, shrouded in mist. The sea is rough with white-capped waves. Art style: dark fantasy, gothic horror, digital painting, highly detailed. Moody, ominous lighting with high contrast. Dominant colors are deep reds, greens, blues, and dark grays. Intricate details on the castle and environment.
