My advice when folks are struggling with writing in the third-person omniscient is
to Lemony Snicket it up. Give your omniscient narrator strong opinions
about what’s going on. Don’t fall into the trap of assuming that the
third-person omniscient perspective must also use the objective voice;
those are two separate things, and many of the most popular and successful writers who’ve written in the third-person omniscient do not, in fact, use the objective voice.
“Willingness to admit the narrative has a voice” is, I think, a big part of what makes young adult literature so much more engaging than a lot of books marketed at adults, particularly adult men.
“Lemony Snicket it up” is a very good phrase and very good advice
