Capture an intimate, close-up portrait of a "Malachite Cyborg," her features carved from smooth, banded green malachite accented with polished brass fittings. Her cybernetic elements spiral with the natural patterns of the stone, glowing faintly with soft emerald light. Fine cracks in her design emit a subtle, luminous energy. The background is a blurred forest lit with dappled sunlight, evoking the mysterious and earthy essence of her form.
