What if a reader gets tripped up by some small part of your book? Perhaps a sentence or a few words don’t make sense to them. Maybe one of your creative flourishes isn’t sitting well. There isn’t necessarily anything wrong with what you wrote, and there may only be one reader or two that have commented. What do you do?
Do you just brush it off and say, “I’m an artist and people should accept all my amazing choices” or do you see it as an opportunity to possibly improve? If you are serious about your craft, I suggest the second choice. You may not end up changing the issue in question, and it could have been brought to your attention by only one soul, but you should seriously evaluate it.
You can’t hope to make everyone happy with your writing decisions, voice and style — nor should you attempt to. Telling your own story is paramount, but fine-tuning your ability to tell that story is not far behind.
I changed three or four sentences in Among the Shadows based on reader feedback. Ultimately, these things had little impact on the overall story, but I could see why some might not like how I worded them. The revisions do read better. Part of being a writer is deciding which creative choices to keep and which to modify.
