Depict a lone wolf standing on a windswept ridge overlooking a vast expanse of icy snowfields. The wolf's fur is a blend of gray and white, camouflaged against the snowy landscape. Its head is held high, ears perked, and eyes scanning the horizon for prey. The setting sun casts a warm glow on the snowdrifts in the distance, while the sky above is ablaze with shades of orange and purple.  Capture the scene with a telephoto lens, emphasizing the wolf's solitary nature and the vastness of its icy domain. Employ a cool color palette with warm accents on the sunset, in a realistic wildlife painting style.
