Strangely enough, If you have a friend/professor who is similarly minded to you (and of course, you dont mind having other people read unfinished work) try having them read it and either give you their thoughts and opinions, or have them, if they should feel so inclined continue on for as long as they desire and simply pick up from there. I've found that sometimes your characters can become somewhat stale, or perhaps cookie cutter is a better description, simply from lack of other insight. You sometimes put to much of yourself into your characters and having someone else contribute can even turn a good work into an extraordinary work.
