E-reader layout

I made both of my designs to fit on to the size of an ipad and a kindle fire. This is how the book cover would look if it was sold as an e-book and to do this I had to resize the cover because the e-readers are longer than my book cover. I think they worked quite well on the e-readers because with just the front cover you can still see links between that and the book with the objects and keyhole shape and I think it would stand out on the screen because of the bold background and contrast of white against it. I also think that the typeface worked well because it is still very legible.
