I could use some advice or reassurance on a matter of acceptable finished manuscript stylizations. I understand that a manuscript should be free of an author's stylizations even those that appear in published books and that it is important to be consistent throughout the piece. However, being consistently wrong throughout the manuscript is something I would like to avoid. My current piece is told in third-person limited with multiple POVs. Most of the time, the POV changes take place at chapter breaks but there is sometimes a scene change within a chapter that also includes a POV change. Most chapters also contain more than one scene, although the POV doesn't always change. Currently, I have been entering a blank line between scene changes where the POV stays the same. If there is also a POV change, I center some asterisks on a blank line. I am consistent with this throughout the entire piece, but I wonder if it's necessary. It becomes clear in the writing whose POV I am telling the scene through, so should all scene changes be a blank line? Or is that not even necessary?
