A monumental oil painting in the style of Rembrandt, depicting an evil witch emerging from beneath an ancient gravestone on Halloween night. The sky is filled with ominous clouds, casting a foreboding atmosphere over the scene. The weather is damp and muddy, enhancing the eerie quality of the painting.
