A hyperrealistic, close- up macro shot of a undead, entirely constructed from shimmering, multifaceted crystals of varying sizes and colors. The crystals should range from clear quartz to amethyst, citrine, emerald, ruby, and sapphire, creating a dazzling mosaic effect. The individual crystals should be meticulously arranged to mimic the anatomical structure of a undead, The eyes should be particularly striking, perhaps crafted from large, flawless gemstones that seem to glow with an inner light. The background should be a soft, blurred bokeh of deep blues and purples, suggesting a mystical or otherworldly setting. The lighting should be dramatic and directional, highlighting the intricate details and the play of light across the crystalline surface. Every facet should reflect light, creating a sparkling, almost hypnotic effect. The overall impression should be one of breathtaking beauty and intricate craftsmanship, a testament to the power of nature and the artistry of artificial intelligence
