This is a detailed JSON-formatted prompt designed for image generation, specifically to create illustrations in a 'Cozy Storybook Illustration' style, mimicking the look of colored pencils and subtle watercolor washes. It includes two specific prompt variations, one focusing on texture and stroke, and another on mixed media watercolor effects. This prompt is intended for style transfer based on an uploaded image.
