Dear Vivaan Singh Bhandari, 🌟 you did an absolutely fantastic job with your cotton rubbing painting of a watermelon, and your teacher loved how colorful and fun your artwork looks, also your creativity really shines through in the way you used the cotton to make the texture of the watermelon. Moreover, it is great to see how you followed the steps to create such a beautiful piece of art, and your attention to detail shows that you put a lot of thought into your work. To make your next project even better, you could try adding some extra colors or patterns around your watermelon to make it pop even more, and remember that experimenting with different techniques can be really exciting too! Keep up this wonderful effort because you are doing such an amazing job, and your teacher is so proud of how much you are learning and creating. You are a superstar artist, and I can't wait to see what you create next! 😊.
