This is a digital illustration full of Halloween atmosphere. The main subject is a Gothic haunted house standing in the night, with spire towers and错落 structures barely visible in the darkness. Several windows emit dim yellow light, as if ghosts are wandering inside. In the foreground right, a giant dead tree silhouette has sinister branches reaching towards the sky. A huge spider web hangs overhead, appearing crystal clear under strong moonlight beams that radiate through the mist, creating a mysterious and eerie visual effect. The overall color tone is dominated by deep blue and cyan, accented with warm yellow lights, perfectly interpreting the thriller and fantasy sense of Halloween, suitable as a festival-themed desktop wallpaper.
