By reviewing your work you can improve it a lot, do it more than once. Some recommendations may be:
Read slowly what you have written and make improvements. You can change expressions to make it more understandable or use synonyms to avoid repeating the same word. Sometimes you can also eliminate them, because they are understood or use pronouns.
Check spelling. If you are not sure about a word, the dictionary is your best help.
