I started out with the cover design for the book:

I used Photoshop to make quick sketches and place the titles to get a general idea of the Cover. The author wanted another approach. A more rusty, vintage look with old books, paper notes and fountain pens.
So I started over and used a lot of photographs to composite a new cover. Fortunately, I have a lot of old books and an old Victorian Writing Desk. I took pictures of my writing desk and books and made some sketches and made this cover in Photoshop.
After that I made a cover spread with the Victorianwriting desk as a background:

Unfortunately the publisher did not like this design
He thought it was to dark for the targeted readers, so I had to come up with a new cover.
So I stripped away all the written notes and old scriptures and made an illustration in TV Paint

The illustrations in for the inside of the book I drew entirely in TV Paint.

Since 3 years I try and draw, paint and animate everything digital. It is much faster and you are more flexible.
I also had to make Titles for the different chapters of the book:
