Currently, I submitted my article to the frontiers series and received comments from the reviewers. After revising the article, I let a native English speaker help me to check it.
She made great revisions for me, especially in improving the writing (eg. grammar/choosing a better word/changing the order of the sentence). Although it was helpful, the reviewers didn't request me to do it. They just evaluated my writing as 3(the full point is 5).
Should I improve all of them according to her suggestions, even though most of them didn't been pointed out in any questions or errors? or do I just need to improve the parts that have been commented on? If I improved and changed lots of the word selections, should I mention all of them in the response to the reviewer/editor?
