Add elements like Santa Claus interacting with children, elves, and families with pets. The background should feature snow-covered trees and a skating rink with people skating. Include details such as garlands, fairy lights, and various holiday decorations. The overall style should be realistic yet festive, capturing the joyful essence of a Christmas market in winter. The image should be suitable for coloring, with clear outlines and defined spaces. Use only black and white for this illustration. The dimensions should be 8.5 x 11 inches.
