Create an illustration featuring a silhouette scene with four figures: two shepherds, a woman, and a man, gathered around a small structure. The background should be a deep navy blue filled with twinkling stars. Replace the central bright star with a glowing crescent moon. The figures should be dressed in flowing, traditional robes and hoods, while a friendly dog stands beside the shepherds. The overall theme should convey warmth and togetherness during a serene night.
