While researching book covers someone sent me a link to a site of a list of books with their redesigns. Each book has its own style and forms a story on the cover.

I liked the design of "The boy with a tigers heart" and thought to use it on "The Last Unicorn" book. So much is happening on the front cover and generates the story itself which interests the reader.
For "The Last Unicorn" I quickly sketched an outline of the bulls head. I was thinking if using the body but it was too long and short for the page. Inside the bulls head will be two waves climbing up the side. These waves will be the unicorns trying to escape the sea which was told in the story. It also shows another term for "white horses" in other words the white from the sea. At the side of the head will be a rocky cliff with trees to form the horns. I'm not sure at this point to leave it at that or to add the main character at the top of the head on a bridge. It's a working progress for now but ideas will change once I get to use illustrator.
Also going through my list I'm thinking of leaving out a few books as I may not have enough time or have no ideas for them. One of them is the "edge chronicles" as the idea for that design might be similar to "The Last Unicorn" and want each books to have different designs. Again I might change my mind and have a go to see what I can accomplish for the design.
