Have you ever checked out fanstory.com? I used to belong, but I have moved on to other writing projects now. It is a GREAT site to submit short stories for critique from other writers. The criticism is useful, not just wishy washy unhelpful stuff. You also get to critique other writers' work. There is a small monthly fee. I think it was 5.95 a month. I learned a lot when I was on fanstory.
