Illustrate a Christmas scene that reads like a haunting ballad whispered by a bard on a cold winter's night. In a dimly lit room, a grand Christmas tree looms, its branches heavy with foreboding ornaments. The centerpiece is a woolen sweater, hung over a chair, its intricate patterns seemingly woven with shadowy secrets. The room is aglow with a sickly green light, casting menacing shadows that dance across the walls like phantoms. Outside the frosted window, snow drifts silently, yet there's an unsettling presence on the periphery of the scene, as if the night itself is holding its breath. Render the scene with an ethereal glow, giving a poetic but ominous quality to the holiday imagery.
