Very spooky, I like it! You did a very good job describing the scene with sight. It would be cool to explore other senses deeper. Maybe smell? Maybe feeling (like how things move slower in cold or how coldness seeps warmth)?
I really enjoyed how you used the teeth chattering, but you did not go into too much depth with it. With your writing skills, it would be awesome for you to go more in detail with how the noises of the cold actually sound. Try to go into more detail like, “the chattering of her teeth sounded like the bite of frost,” or, “Her breaths were sharp and caught on the cold”. Just try to describe the senses in a creative way using descriptive words from other senses.
Overall, you did a wonderful job, and this piece gets me into the mood of cold weather :D
