Highly detailed close-up anime-style digital illustration of a silver-haired girl with long ponytail standing firm in a deep, wide horse stance, her feet submerged in the icy, foamy water of a snow-covered beach. She wears a white karate uniform and a white belt, her face calm and focused. Her mouth is slightly open. Snowflakes fall steadily as the cold waves lap against her bare legs, and her white karate uniform is dampened at the hem. The gray, stormy ocean contrasts with her focused expression as she strikes a sharp, controlled punch. The muted lighting of the overcast winter day enhances the determination in her eyes, while the freezing environment emphasizes her resilience and discipline.
