As a brand new author I want to know what you all think of my work. It's important to me to know that you like it and why or that you hate it and why. Such information helps me to improve the next piece of work. I have come to realise that there is a huge difference in the types of feedback you get from readers as opposed to writers. Both are useful and welcome.
When writers give feedback, they tend to concentrate only on the mechanics of your writing. They'll will moan that you've used too many adverbs, used too little punctuation, used the word 'had' too often and so on and so forth. This stuff is very useful to a writer like me, who is self taught and learning as she goes along. Taking this type of feedback on board can make your next piece of work better in a mechanical way and will help to get you known as a 'good writer.'
When readers or should I say, non writers give feedback they never say that stuff. They will tell you that they loved it, hated it or got bored half way through. They will tell you they were gripped, that they couldn't put it down or that they forgot it when they did. They will tell you they found your characters believable and interesting, that the locations were real, that they could see it in their heads as they read. This is the kind of stuff that tells you if your story is basically a good one, despite the mechanics.
Both of these different kinds of feedback are useful and give you valuable information that you can use to make your next work even better.
