I may never be satisfied -- so I've left fate in others hands.
Upon several recommendations, I joined the online writers workshop (http://sff.onlinewritersworkshop.com/) where writers review and get reviewed, plus additional resources for the barely literate. Finally, a chance to gather opinions from total strangers. I'm not sure how many samples I'll submit; just depends upon feedback and usefullness.
Lots of great writers out there. I just checked out a member's website ( Ian Tregillis ), who is soon published by TOR...for the next three years. Great stuff. Phenomenal writing. I won't even pretend to ever write that well. And he's not the only one.
