My guardian spirit

1st person, a boy around 12 years old with long, black hair that is curled inward, black, round eyes, a yellow shirt, a red bow tie, black pants, suspenders, a smile, and a relaxed demeanor. 2nd person, a guardian spirit, a boy with messy black hair, hollow eyes, dark circles under his eyes, a white shirt, a yellow vest, a red tie, khaki pants, a hunched back, a gloomy face, and an eerie presence. The guardian spirit is slightly transparent and is standing behind the human boy. Both are of similar height. The background is a peaceful park with trees and grass, and the blue sky is filled with flying white birds.
