First time using forum so don't know if I should edit or reply like this.
Reply is always best, so others can follow the conversation.
One suggestion I can make is to use one of the free editing sites, like Grammarly. It helped my writing a lot, helping me catch most instances where I used a wrong word, or a phrasing that could be improved. But feel free to ignore a suggestion if you like it as it sits.
Also, many times if one of the editors here likes reading your works, they will send emails with corrections. I have at least 3 that do that for me, and it helps catch the other things I might have missed.
And using software like Grammarly does help, if used correctly. To give an idea, my second drafts when I plug them in normally score around 70, and after editing that will be increased to normally from 82-90 (depending on story).
Lowered a bit because I tend to use "familial" wording or "extra words" that it thinks are not needed, but I do (it does not like "actually" or "really" and always wants to remove them, hates "sometimes" instead of "sometime", "anyways" instead of "anyway", and things like that). And my first person narrations always score lower than my third person ones do. But in general anything that scores 80 or above is pretty good for the most part.
I think on average my volunteer editors now maybe find 1 correction per chapter on average. A vast improvement from 2 years ago when I would get dozens per chapter.
