Ancient Castle Ruin in Dark Fantasy Style

A dramatic and mysterious digital painting of a huge, ancient, and crumbling castle with an imposing presence. The castle is overgrown with moss and ivy and is silhouetted against a cloudy sky. The lighting is dramatic and moody, perhaps with a hint of sunlight breaking through the clouds to highlight parts of the ruin. The artistic style is epic fantasy or dark fantasy concept art, with a focus on scale and a sense of forgotten history. The mood is somber, majestic, and a little bit eerie.
