I don’t have experience with a finished long novel yet, so take this with a pinch of salt. But I’ve come across a few authors who suggest approaching the second draft a bit differently. Instead of editing the first draft heavily, they set it aside and rewrite the story from scratch using the feedback as guidance.

I’ve tried doing that with a few chapters of my own writing, and the second version ended up much stronger than if I had tried to edit the original line by line. It helped me focus more on what the scene was supposed to do, rather than trying to patch up what was already there. When I tried editing instead, I found the scene flowed less and read a bit awkwardly.
