Those lucky enough to stumble upon this magical creature, are granted a wish to convert anything they want, in gold. It has been rumored they last over a thousand years. Their horns are composed of bone at birth, and with age, they slowly transition into gold.
Initial sculpt started in Blender, then brought over to ZBrush for detailing. All details are hand sculpted. Digital paint in Substance Painter. Rendered in Blender/Cycles. All compositing, editing and color correction also done in Blender.
