First of all, you are right to think that your composition is better, because everything needs a good attitude! If you want to always feel that your composition is good, then you must find ways to make your composition icing on the cake!

how can I add icing on the cake to my composition?

first of all, you need to read a lot of extra-curricular books, essays and compositions, which is the best choice. Moreover, it is good for you to read carefully and draw metaphors, anthropomorphic sentences or explanations and beautiful words with appropriate symbols. When writing a composition, you should first write sentences fluently, grasp the center, and don't have sentences unrelated to the center in the article. For example, if you want to write about one person and your mother, then you must grasp the face and characteristics of your mother and never write about two people! Finally, use some beautiful words, preferably metaphors and essays! Remember, using these will definitely make your article the finishing touch! Write more compositions at ordinary times!
