Her petite silhouette is brought to life through refined sculpting that emphasizes slender limbs, a gentle neck, and a softly curved spine. The head turns slightly as if listening to an unseen friend, with large, expressive eyes, a subtle smile, and hair arranged in neat, understated styling. The overall color palette favors soft pastels and muted tones, enhanced by crisp paintwork and careful shading to highlight skin, hair, and fabric folds. The pedestal and base design are understated to keep the focus on the figure's quiet elegance and charm.
