You might want to try a critique group instead
Annie,
I think you'd do better with a critique group. A regular meeting of serious writers, who write the same material (novels, poetry, short stories, etc.) can provide you better and ongoing feedback for years. You benefit from the synergy of a group, where one persons comments and that gives another idea to another reviewer, etc.
A critique group helped me whip my novel into shape (published by HarperCollins in September 2006), and they really helped me tighten up and perfect my writing. And that's aside from giving me plenty of ideas and plot suggestions.
Be warned, a critique group of serious writers is not for the faint of heart. You'll hear lots of things you may not like, or agree with. But it can make you a better writer.
That said, finding a good critique group is very difficult. There are lots of them out there, but most of them aren't really serious. It takes some work, but you can usually find 3-4 serious writers who are looking to improve their craft, and if you can get in one of those, it's worth the search.
Let me know if you want to know more about CGs.
