Create an intricate and highly detailed digital artwork of a humanoid face that merges organic and mechanical elements. The left side of the face features natural, tribal-like patterns, symbolizing ancient cultures, while the right side blends futuristic machinery with tribal designs, creating a seamless fusion of nature and technology. The face is adorned with intricate symbols, representing a harmony between past and future civilizations. Set the artwork against a dark, atmospheric background featuring a celestial body, such as a glowing moon, and floating particles to add depth and mystery. The piece should evoke a cinematic essence, rendered as a high-quality 3D artwork, painting, or conceptual illustration, with a strong focus on light, shadow, and texture to create a visually captivating and thought-provoking composition.
