First, I apologize humbly if I was too harsh on your excerpt. I don't recall if it was one of the ones I gave feedback on. It's true that an unpolished excerpt runs the risk of getting lots of critique... A polished excerpt has other risks attached. We're all doing our best.
I like Maryn's answer ... and did basically that, for my current historical fiction project. Then I wrote opening pages in the style of four of my favorite books, out of perhaps a hundred looked at. THEN I put the first two hundred words of those four openings up to see what other people, here, thought.
That post is here and you can see there are four different 'page one' excerpts in the first post, and critters ranked them for me.
I remain so, so appreciative of everyone's feedback on that thread.
One of the things I learned was that different openings were liked by different people. Big surprise, I guess? Maybe not? In the end I chose to take two of them which did marginally better overall, and I'm now developing into two different versions of the same basic story.
It sounds like a lot of work, and it is, but this whole writing thing is so hard already I figured I might learn something new by taking a different approach.
So, in
your shoes, I'll second Maryn's advice. Read lots of 'page one' openings at the library or wherever and try to figure out what is working for you in that opening.
Also, remember that although this is a big forum, it does not represent readers across the board and across the world. Your opening might be great as it stands! All we can do is try to help each other and have a good time.
