Keep the same character from the reference image, preserving her recognizable features and proportions. Slightly adjust the art style to be more playful, expressive, and comical. Dress her only in an oversized white bedsheet ghost costume, with no additional clothing or accessories visible. The sheet covers her body, while her face peeks through an opening. She faces the viewer with both arms raised beneath the sheet, attempting an exaggerated spooky pose but looking hilariously unconvincing. Emphasize her mischievous expression, awkwardly dramatic gestures, and the floppy fabric draping over her arms. Keep the background simple and the Halloween mood funny rather than frightening.
