A majestic mythical phoenix made entirely of crystalline blue ice and frosted snow, taking flight from a vast glacier. Intricate ice crystal feathers with glowing cool blue inner light, frosted snow swirling dynamically around its expansive wings. Cinematic composition, dramatic lighting from below, deep blue and white color palette, ultra-detailed, 4K resolution, ethereal frost particles floating in the cold air, majestic soaring pose, glacier reflecting icy blue hues.
