Design a menacing skull mask without a jaw that exudes a devilish and demonic aura. The mask should have sharp, angular features with intricate, hellish textures. Incorporate elements like horns, fangs, and glowing red eyes to enhance its fearsome appearance. The surface of the mask should have a cracked, burnt texture, as if forged in the fires of the underworld. Use dark and deep hues, such as black, crimson, and dark grey, to give it a sinister and otherworldly feel
