I'm not a skilled writer like anyone else here. Simply a novice, so any thoughts I have on the matter should be viewed with caution and only considered after all else.
Though I cannot say what is proper, I can say what I'm working on now has changed my personal style considerably. In the last novel I wrote, a rather substantial 211k-words with considerable research, though I had close to (maybe) 75 significant characters, virtually everything was from the protagonists viewpoint in varied POV's because she is a bit deranged.
(though let me take that back a minute. I do have a few scenes in a bunkhouse or cook-shack with 20-characters (each with distinct personalities and manners of speaking), or even lynch-mob scenes where it is pure chaos regarding characters and PoVs. However, that chaos actually immerses the reader into it, not only seeing the action, hearing the varied discussions, yet makes them feel they're right in the midst of it)
It worked well, and that's fine. On this latest work however everything seems to have changed.
What follows goes against everything I have read regarding POV's and characters within a story... Yet, I'm doing it.
My protagonist gets big chunks, so does my deuteragonist, the long gone antagonist, etc., etc... Pretty much anyone who is mentioned in name, even casually at some point seems to be the absolute focus (from their viewpoint) no matter how briefly.
Considering 1stP-POV, 2ndP, 3rdP, 3rd-Omni, 3rd-Lim... I have read to pick-it and stick with it. I however have found myself even floating a bit there... however, once again it is working well. It has made the story more readable and even make more sense.
Point being >>>for myself in this work<<< abiding by the hard fast rules made the story read poorly, made it seem artificial and less immersive. By simply writing and not sweating what is considered a proper POV writing style and character representation, instead makes the story feel 'genuine.'
Feedback from readers has been great... Feedback from those who fancy themselves as editors first, readers second has focused upon how I broke this rule or that (yet when I ask them how was the story, did those 'errors' hurt it, they had no answer).
So, I suppose you need to decide who you're wanting to please (is perhaps the best way I can put it). Your editors, your readers or yourself and combinations thereof? And, does it work?
IOW, are you perhaps sweating the 'rules' too much and disregarding what works?
Once more, I am a NOVICE writer. So please take everyone else's thoughts over mine.
