A cozy and refreshing illustration of a year-end cleaning finale in a Japanese-style room. A woman in her early 30s with ponytail hair, wearing a casual T-shirt and jeans, stands by an open window taking a deep breath with a satisfied smile, her eyes closed and hand on her chest. At her feet, a fluffy calico cat sits contentedly, leaning against her leg with half-closed eyes. The room is spotless: polished wooden floor gleaming, large clean window letting in soft winter sunlight and a gentle breeze that sways the curtains lightly. Organized shelves in the background with empty spaces from decluttering, a new notebook labeled “New Year’s Goals” on one shelf, and a fresh potted plant nearby. An aroma diffuser on a table emits soft steam, next to a steaming cup of green tea. End-of-year elements include a 2026 calendar on the wall open to January 1st, small New Year’s decorations like a mini kadomatsu and kagami mochi on a shelf. Cleaning tools like a broom and bucket are neatly stored in the corner. Overall atmosphere is bright, refreshing, and warm, with cool blues and warm yellows, in a cute illustrative style.
