Create a standalone eerie boy’s severed head with a sinister, unsettling expression. The head should feature hollow, wide eyes, a faint twisted smirk, and pale, lifeless skin. Include messy, short hair styled to suggest attachment to a chain. Ensure the design looks haunting and dark, avoiding cheerful or playful elements. Focus solely on the severed head without any bust or shoulders, creating a gothic, disturbing aesthetic fit for a Krampus-themed display
