I wonder if you might want to reconsider posting your chapters in pieces. By the time you have an entire book published on site, you're going to be stuck with a pile of pieces and an enormous number of reviews to sift through if you want to make changes, go back to your original, or just re-read to make sure you've got what you want!
You may be doing this in sections to make it easy on reviewers, to offer us the benefit of extra points, or maybe you have so much to say you just want to post it right away, but think about making things easy on yourself in the long run. You've still got a long way to go.
I am enjoying your story--keep up the good work. JP
