For the image of midlejourney, a bot that provides assistance with a wide range of tasks on openai, i envision a sleek, modern design with a friendly and functional feel. the color palette should consist of varying shades of green and white, with a gradient background from dark green at the top to light green at the bottom. midlejourney itself should be depicted as a compact bot with a circular "head" and bright, expressive eyes on a white background. simple yet elegant, the overall style should be clean and linear, with minimalistic details. the image should be in png format with a resolution of 1000x1000 pixels, and created in vector format for high-quality output and easy scalability.
