Moonwriter, if we were all awaiting a response (positive or negative) from the readers to our stories before continuing, then I'm afraid most of us wouldn't get to part 2. Don't worry if no one has responded. I would take a guess that 90% of these stories don't get a response, that's just the nature of the "business".
I write for pleasure, if there is a response, fantastic, great, but if not well...I carry on anyway. If you genuinely like writing, the more you write, the better (I think) you get - and the more pleasure you get from doing it.
So please carry on writing, do not stop, not having a response is no reflection on your story whatsoever.
