Design a logo for an AI model agency named 'Roya' featuring a half

Design a logo for an AI model agency named 'Roya' featuring a half-human, half-bot face. The logo should seamlessly blend these two elements to represent the merging of human creativity with artificial intelligence. On one side, illustrate a human face with soft, realistic features, showing warmth and emotion. On the other side, design a robotic face with sleek, angular lines, incorporating circuit patterns or digital elements to convey a high-tech feel. The transition between the human and robotic sides should be smooth, symbolizing the harmony and integration of AI with human traits. Use a color palette that includes metallic silvers and grays for the robotic side, contrasted with natural skin tones for the human side. The overall design should be sophisticated, futuristic, and convey a sense of intelligence, innovation, and artistry, fitting for an AI model agency.
