I am disappointed in this product. It has none of the benefits of it being a PDF.
I don't mind the parchment background, but the fake binding border (all on the same side too) takes away from it.
The (See "Ptolus: City by the Spire", page xxx) would be nice in a table of contents or in bookmarks. Not part of the picture.
Your logo and telling us which sketchbook it is on each black & white page is a waste of space and ink.
When there are two pieces of art on one page, some of them are at 90 degrees of the other. So you have one right side up, and another sideways.
Only with some serious doctoring will I print this out. Even if I paid half price this would get only 2 stars out of five.
After seeing your work in the Ptolus previews, I'm surprised and appalled.
