Generate a coloring page for kids that depicts an exciting, joyful, and cheerful scene. In this scene, two Brontosaurus are playing in the water, showing clear signs of happiness, excitement, and laughter. Surround the Brontosaurus pair with trees, and include a large sun behind them with fluffy clouds in the sky. The atmosphere should be brimming with joy and energy. To enhance the prehistoric atmosphere, add flying extincted species in the sky. These could be pterosaurs or other dinosaurs that have long gone extinct. 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 outline the characters, elements in the scene, and the flying extincted species clearly. Let the chaos parameter be set at 60 to introduce some unexpected elements that enhance the playful atmosphere. 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, maintaining the simplicity and clarity required for a coloring page. Use the uplight upscaler to enhance the level of detail in the final image while preserving the simple outlined style suitable for coloring. Thank you, Midjourney, for helping us create this exciting and joyful coloring page featuring two playful Brontosaurus in the water, with flying extincted species in the sky!
