Hi Mark,
Maybe you could post a portion of it, say a few paras, get some comments and then later on more. I feel sure that a short excerpt from the text will give the reader some ideas and feel for the essay. I know when I read something, its the first few lines which "Talk" to me. So maybe a portion of this would help to gain enough comments to give you some ideas.
If you want to send me some reading - I would be glad to take a peek.- books in Holland cost a fortune!!! Im finding the work I receive from Writers Circle is keeping me in reading material and that is so interesting, better than buying the books I think!!
All the best with this
Lin
