Character concept art sheet, multiple angles, full-body view, side view, and detailed close-up of the weapon. A White Walker from A Song of Ice and Fire, based on George R.R. Martin's description. An ancient, beautiful, and deeply strange being sculpted from ice. Elegant, aristocratic, and majestic rather than beastly. The skin is translucent, milk-white, with bones softly glowing with a pale milk-white light from beneath the surface. Eyes glow like brilliant blue starlight. Wearing armor made of a strange shifting ice, displaying subtle alternating shades of blue-green and grey-white, with a reflective surface changing with the environment like a still lake. Cinematic lighting, ethereal and supernatural atmosphere, fantasy art style, ultra-detailed
