My writing group lately has been harrowing me to stop using 3rd Person Omniscient perspective and use 3rd Person Limited instead. Brandon Sanderson (I'm part of his writing class and will be again next semester) has said that it's gone out of favor and publishers accept fewer works that use it. His debate against using omnipotent is that it can be confusing for the reader. I'll give an example from one of my books where I can see their dilemma:
Yūjin picked up his pace, moving even faster than before. Juko could scarcely believe it. Yūjin was only taller than him by a couple of inches, but he seemed to be able to move much faster than he did. He forced legs to move faster to keep up with him.
Sōan was straggling behind. The two of them moved way faster then she could possibly even believe. It was like they weren’t human.
“C’mon… Sōan…” she huffed, “You can’t let… those boys… beat you now… can you?”
She tried to control her breathing, focusing on the two of them, with their backs continually increasing their distance between her
In this one scene, I simultaneously switch between three character's perspectives, and it's confusing who is thinking what.
As I've recognized this problem, I've started to focus on one person per chapter; however, I've run into another problem. As I write from a limited perspective, the feelings and thoughts of the other characters (who I consider main characters as well) are left in the dust. Also, scenes that I've written lose meaning and context without the thoughts/expressions/feelings of the other characters.
TL;DR
How do I write in 3rd Person Limited Perspective without losing the depth I've built into my other characters? (Note: I'm talking about writing as a whole, not just this specific scene)
Yūjin picked up his pace, moving even faster than before. Juko could scarcely believe it. Yūjin was only taller than him by a couple of inches, but seemed to be able to move much faster. Juko forced his legs to move faster to keep up with his friend. Sōan was straggling behind. Yūjin and Juko moved way faster then she could possibly even believe. It was like they weren’t human. “C’mon… Sōan…” she huffed to herself, ... focusing on the two boys, ...
Put this beside your text and compare what I changed. There are some other minor stilistic issues, but nothing fundamental.
