Generate a coloring page for kids that depicts a captivating prehistoric scene. In this scene, a pterodactyl should be hovering high in the sky with its child flying behind it. The sky should have a cloudy sunrise appearance, creating a sense of awe and wonder. Far below in the scene, include a landscape with trees, a lake, and ten mammoths walking. The mammoths should be walking peacefully, and the entire scene should convey a sense of harmony between the pterodactyl family and the prehistoric world. Ensure that the image has an aspect ratio of 2 to accommodate the landscape format suitable for coloring pages. To maintain the simplicity required for a coloring page, instruct Midjourney to use only lines without any colors or shades. The lines should clearly outline the pterodactyls, the landscape, and the mammoths. Set the chaos parameter to 60 to introduce some unexpected elements that enhance the sense of wonder in the scene. Maintain a rendering quality of 1 to balance detail and rendering time. We want a single variation of this image, so set the repeat parameter to 1. Use a seed value of 987654 for consistency in the randomness of the generation process. For the style, select the 4b model to ensure a style suitable for kids' coloring pages. Adjust the stylize parameter to 800 to moderate the intensity of Midjourney's default style in the output, ensuring the lines remain clean and clear for coloring. Use the upbeta upscaler to add a bit more detail to the final image while keeping it suitable for a coloring page. Thank you, Midjourney, for helping us create this captivating coloring page featuring a pterodactyl family, a cloudy sunrise sky, and a prehistoric landscape with mammoths, perfect for coloring by kids!
