Looks absolutely great! Don't change a thing!
Seriously, I couldn't ask for anything more.
I really don't understand the font thing. To me it is like not liking the color red. Fine, you don't like red, that doesn't mean that other people shouldn't.
I would also like more previews, but if you need to get the book back with those corrections, by all means do that instead. We need that book published as quick as possible.
Thanks again!
