Create a captivating collection of traditional Japanese dolls for an enchanting children's coloring book. Each doll should be presented in a delightful black-ink-line style, capturing the elegance and beauty of these cherished cultural symbols. Illustrate each Japanese doll separately, ensuring they do not overlap, and use black ink lines to define their shapes and intricate details. The outlines of the dolls should be drawn with thicker lines, giving them a charming and distinct appearance, while the finer elements like elaborate kimono patterns, accessories, and facial features should be depicted with softer lines. Include Japanese dolls of different types, such as Hina dolls, Kokeshi dolls, and Daruma dolls, each representing unique aspects of Japanese culture and tradition. Each doll should evoke a sense of grace and history, making them fascinating subjects for coloring and learning about Japanese heritage. To complement the black-ink-line style, keep the background white with no added text or colors. This will provide ample space for children to add their own artistic touches, exploring the world of Japanese art and aesthetics as they bring these traditional dolls to life through coloring. The overall style of the illustrations should be captivating and educational, encouraging young artists to appreciate the beauty of different cultures and embrace the joy of creativity through art. --v 5.2
