A detailed human skull cap (cranial top), showing realistic bone texture and subtle imperfections. The surface is slightly rough, with visible sutures connecting the parietal and frontal bones, and faint cracks and pores adding to the naturalistic detail. The bone has a weathered, off-white appearance, with areas of discoloration suggesting age and exposure. The overall design is anatomically accurate, with moody lighting emphasizing the ridges and crevices of the skull.
