Enchanting Book Cover Design for 'Alice Winter and the Winter’s Key'

Design a captivating book cover for "Alice Winter and the Winter’s Key." The cover should feature a snowy landscape with gently falling snowflakes and a dimly lit forest in the background. In the foreground, depict a young girl named Alice, with an expression of curiosity and wonder, holding a tarnished silver key that glows faintly. The title should be prominently displayed at the top in whimsical, frost-like lettering, with a subtle shimmer effect. Incorporate elements of magic, such as twinkling lights in the trees, to evoke a sense of mystery and adventure. The overall colour palette should be cool blues and silvers, creating a wintery, enchanting atmosphere.
