Color aesthetics: A typical **high-key** color scheme is adopted. The color saturation is moderate, mainly relying on soft pink, cream, and dark blue to create contrast, forming a visual perception that is both warm and steady.

Light and shadow expression: An advanced version of **Cell Shading** was used. The edges of shadows are clear but the transitions are natural, especially in hair and clothing folds. A small amount of gradient color was used to add a sense of thickness to the objects, rather than a rigid stacking of color blocks.
