Oranges are not the only fruit- Thumbnails

As I was reading through Oranges are not the only fruit I started sketching down some thumb nails for the book cover, they are very rough so don't mind the terrible drawing they were just to give me a few ideas in terms of composition and what kind of imagery I wanted to include on the front. When reading the book I was finding it hard to just picture one image that would work for the story so I drew up lots of very different sketches, using different parts of the book for imagery, to see what ideas that I think worked best. 
I decided from this that I liked the idea of using the top of the girls head and a thought bubble with the title of the book inside it. I liked this idea best because you cant see the characters full face, leaving some room for the readers imagination. I also thought this idea fit the way that the book is written well because its written from the girls internal monologue and her thoughts. I will now start to develop this idea further to see how it goes.
