There's one nifty little trick that many writers use but most writers forget to do. It's quite simple. read your work aloud. I have mentee who never met comma she didn't like. She started reading nher work aloud and magically all the commas fell into the right place. if a comma is in the wrong place it wilkl become painfully apparent when you read it aloud. This is very simkple but true.
Good luvk with your writing.
