Focus Group Test for Cover

Most people i asked thought that i should try and show all of the characters on the cover. I intend to do that, by  maybe putting the main two on the front, and a couple more on the back maybe. They also thought, most of them, that i should have text at the top of the back page, and then a couple of pictures in the middle. The majority thought that i should have ratings and reviews somewhere on there so i will try to include those as well.
