Here's a concise English prompt that captures the core elements of the image:

 Anime girl with blonde twin tails and cat ears, winking playfully, sitting on a thick white knitted rug in front of a cozy fireplace. She wears a green military jacket over a white shirt, a beige scarf, and loose white leg warmers, barefoot. A small plush reindeer rests on her shoulder. The room is warmly lit by the fire, with a steaming coffee cup and a vintage lantern on the mantel. Outside the window, a snowy winter forest is visible. Soft, warm lighting, detailed anime illustration, cozy and heartwarming atmosphere.
