So I either send it to my critique partners (sometimes, "again", because they might have seen parts or the whole thing as I tried to get that first draft down) and/or beta readers, depending on what I feel is right. If my critique partners have already read it as I wrote and made changes and agreed on that, then I'll send it off to my betas.
Either way, whatever you choose, you'll get feedback. Probably a lot.
Now if there are big things wrong with your story, you might get similar feedback from different people. Great. That means they all see the same thing, and something is definitely wrong with your story. Brainstorm. Write different scenes. Do whatever it is that works for you, but fix it. And then check with your betas again (or check with them as you go... which is what I do.)
That first option is great. It's a clear message, and a good indication that something bigger is wrong with your story.
But what do you do when everyone seems to say something different?
Well, that happened to me with my first story.
I was lucky enough to have betas who loved my story -- and they all texted me at the same point in the book, asking me how I DARED do that. I remember I smiled so widely my cheeks hurt, and how I seemed to burst with happiness. Those Big Impact Moments worked, and it's a really great feeling.
But I also had smaller, mixed comments, and I found it tough to wrap my head around those at times.
Go with your gut.
I had very small comments that made me think: A-HA! Or: How did I not see that? If comments make you feel that way, your betas are probably right.
But then there were comments that I wasn't sure about. They seemed valid, but did I really feel the same? I wasn't sure.
Give it some thought. Sleep on it. Read the scene again a few days later, and try to see it in a different light with the feedback on your mind. Can you see where they are coming from? Does it make sense? And most importantly: if you go with what they suggest -- or go with whatever you think is the solution to the comment -- will it make the story better?
Will you always get it right? Maybe not.
Although I really enjoy revising (probably more than the struggle of a first draft...) I had a couple of comments that I found really tough to decide on. I remember one of my betas, Jenny, commented that she felt one of my MCs didn't open up enough, but none of my other betas had really said that... So after careful deliberation, I didn't do anything with her comment.
And you know what? Months later, someone I really, really trust (like, if she suggests anything, I'll probably go with it straight away), told me the same thing.
So I changed it. And I went back to Jenny, saying she was right, and asked her opinion on the revised scenes.
Whatever you decide on, revising will often be an ongoing process. Even after your CPs and betas have read it (and numerous revising rounds have followed), you might get feedback from an agent and that can open up a whole new world for your book.
Bottom line, go with your gut. Really listen to what other people have to say, and don't take it personal. Good betas won't tear your book apart -- they'll help you make it better. Does that mean their comments won't hurt? No, it might still sting if you think you really nailed something and they tell you it's not working.
But in the end, your story will be better for it. You will grow as a writer. And that's a journey on its own.
Hope this was helpful. Good luck and happy revising!
