Create a whimsical watercolor illustration in <bellacutie_style>. Depict a character dressed in a traditional Japanese kimono adorned with cherry blossom patterns. The kimono is predominantly white with pink and green accents, and it is tied with a pink obi. The character has long, flowing white hair adorned with a floral headpiece featuring pink and white cherry blossoms. They are holding a small cherry blossom in their right hand, and their left hand is resting on a branch with green leaves. The character is wearing traditional Japanese sandals called geta, which are wooden and have a simple design. The background is a light gray, and there are scattered cherry blossom petals around the character, enhancing the cherry blossom theme. The character also has a small, delicate butterfly wing attached to their back, adding to the fantasy-like appearance. The image is signed with the text "小A老师" in the bottom right corner. Use dreamy and expressive brushstrokes, fluid transitions, splattered paint effect, and an artistic splash aesthetic to bring this enchanting scene to life.
