What is the name of the movie about the little angel that likes snow?

The movie you're referring to is likely "The Snowman" (1982), which is a short animated film based on Raymond Briggs' picture book of the same name. It features a young boy who builds a snowman that comes to life and takes him on a magical adventure. While not specifically about a little angel, the film captures the enchantment of winter and the joy of friendship. If you meant a different film, please provide more details.
