Create a terrifying drawing of a witch wizard. This mage is a being of darkness

Create a terrifying drawing of a witch wizard. This mage is a being of darkness, his face is skeletal, with sunken eyes and no pupil, just a burning flame. Its skin is stretched like parchment and covered in mysterious runes that seem to move. On his head he wears a wide-brimmed hat, the shadows of which hide his face, and dripping from it dripping with melted wax, as if the hat were a lighted candle. His torn black cloak seems to be made of living shadows that stretch into infinity. The mage holds a twisted staff with a human skull at the end, and a dark, slimy substance oozes from the skull. Surrounding him is a circle of candles that burn in green flames and give off a sulfurous smell. The background is dark and filled with sinister shadows.
