Skull-Built Haunted Mansion in a Nightmare Forest

A horrific haunted grand mansion meticulously constructed from thousands upon thousands of stacked skulls, forming a house of horrors. The front door is an open, gaping maw of a skull, revealing a pair of malevolent red eyes within the abyssal darkness. This macabre dwelling is encircled by a fence fashioned from intertwined bones, standing starkly within a nightmarish forest of deformed trees and ghastly, swampy ponds. Rendered in a surrealistic horror art style, with a striking palette combining vivid reds, sickly yellows, somber grays, and toxic greens. Inspired by the unsettling visions of Zdzisław Beksiński and H.R. Giger, with dramatic chiaroscuro lighting casting long, sinister shadows.
