Create a detailed illustration of a skull that looks ominous and dangerous. It should be shown in a three-quarter view, with the skull facing slightly towards the viewer. The skull should have sharp teeth and empty eye sockets, with cracks and markings on the surface of the bone, giving it an aged and menacing look. The background should be dark and ominous, with shadows and eerie lighting to add to the foreboding atmosphere. The overall image should convey a sense of danger. | Anything
