revising the overall structure and flow of your writing

Answer 2

The best answer for this question would be: None.

Because the parts of the stages in writing like

correcting errors in grammar
correcting punctuation errors
correcting spelling errors

are all part of proofreading the writing structure that you have. While,
revising the overall structure and flow of your writing, is the one of the last things to do before confirming the final composition.
