Like you guess this is "The Nutcracker" in the main role Damian as the nutcracker. The princess staring White Book-Mark and Grey Book-Mark as the rat king. Damians horns are outside becuase he is angry that his boyfriend gets kidnapped. In that moment I thought about Mario and Princess Peach who always gets kidnapped.XD Only 4 days left until Christmas and only 4 more picture til the end of this advent calender.
