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.

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.
