An ancient, moss-covered automaton stands guard in a forgotten jungle temple, overgrown with bioluminescent flora. Vines snake around its metallic limbs, and its optical sensors glow with a soft, ethereal blue light. The atmosphere is mysterious and serene, captured in a painterly style that blends elements of steampunk and art nouveau, inspired by the intricate flowing lines of Alphonse Mucha and the biomechanical surrealism of H.R. Giger. Soft volumetric lighting filters through the dense foliage, illuminating intricate details and creating a moody, dreamlike ambiance. Studio lighting, high detail, moody atmosphere.
