I have to agree with Nartwak. The fact is, you've got to have a thick skin when it comes to asking for opinions. That, and you really shouldn't ask for opinions unless you want them. The fact is, you've got to be willing to listen to some painful comments if you want to improve your writing.
HEHE: For example, using redundant statements, misspellings, and run on sentences are all bad, and that's not even getting into the real heart of your writing like plot-lines, pacing, and all sorts of other stuff that make or break your writing project and don't get me started on something really hard like research.
