A majestic woman standing in a frozen palace carved from crystal ice, wearing an elegant silver-blue gown with frost-like embroidery and translucent layers that shimmer like snowflakes. Her long hair flows gently as if moved by a cold breeze, and a delicate ice crown rests atop her head. The full moon glows behind her, casting pale light across snowy mountains and auroras in the sky. Highly detailed fantasy digital painting with cool color tones, luminous highlights, refined linework, and an ethereal winter atmosphere.
