I know I have seen posts from people in the past recommending you not do that because plagerism is alive and well. The posting of final works happens AFTER submission.
Best to contact people directly who offer to look and critique. Elsewhere I have made this offer. SO, if you want me to pull it apart for you, feel free to send me a Private Message. I have done this for Ext 2 students for the last three years.
As you can see from my siggie, I am an aspiring author. Not yet published but close. As close as one can get without the contract in hand (I am told).
