....the pages 20 and 21, shown here, are in rough sketch form. This allows the editor the chance to review what the artist has interpreted from the supplied manuscript. We are only showing One two page spread as the book contains 16 spreads and would be a little redundant to explain the same proceedure repeatedly.
The Editor reviews the sketches and makes any modifications at this phase. If the Editor wants changes after this point it gets a little expensive, as the Illustrator has to change the Illustratiion in question, to conform to the changes requested. Kinda like building a house and changing the blue prints after the fact!
We will show you the sketches, when we get them back from the Editor, that reflect any changes. Until then, have a great day.
