The feedback was basically savage. But then, I knew that this chapter was flawed, it's the "problem child" of my book, it clunks in spots and is okay in others. I heard a lot of useful observations - most importantly, and what nearly everyone said - that it's an action chapter which lacks tension and drama because the reader has no attachment to the outcome of the action or the fate of the characters.
Still, they all said they'd like to read more, and assuming that wasn't just fluffery, now I get to show them the much superior subsequent chapters. In talking over the chapter after everyone's critique, I got them excited about the concept. Lesson learned - I need to not be attached to the format of the book following the characters (ala "Song of Ice and Fire") but instead, following the story.
I've got good ideas, and some high hopes. It was a good meeting, and I took some tough knocks - but it was from people who really know their stuff. One of them said, "I think you've got a great idea, and I'll kick your ass if you do it wrong."
I'm excited. I'm a writer!
