I hope you all don't mind if I add to your discussion. I've been a member of an online writers' group on Kelley Armstrong's web site for the last 2 and a half years.
Reading some of the comments on the last page here has prompted me to give you a bit of advice.
It's nice to have people give you critiques on your work; but by far, you learn more about writing, and become a better writer, by critiquing the work of others.
When you are doing a critique of someone else's work, your mind is open, looking for what makes the work good, and what needs to be improved; so you are actively thinking about the elements of good prose. That active thinking sooner or later penetrates the cerebral cortex, and is adopted by the creative side of your brain.
One more bit of advice, if I may. When someone critiques your work, there are basically three responses you will have to their input:
1) "Holy cow, batman, why didn't I think of that?"
2) "Mmm. That's interesting. I'm going to have to think about that one."
3) "Well, this person obviously has no clue whatsoever."
And that's as it should be. Because only you are the creator of your story.
