Don't Judge a Book by its Cover

I think there's a lot of things that can go wrong with book covers. If you put too much on a cover, it'll seem too crouded. On the other hand, if you dont put enough detail on it the cover will look underdeveloped. If you try to use a simplified image, a lot of times it'll make the cover look childish and no respectable adult will want to read it. If you make it look too adult or gruesome, however, many people probably won't even pick it up. In the case of a series, you've got to make sure the covers all work together in some way or another. A great example of this is Oliver Sacks' collection of covers. He made all six of them work together to create one image when they come together. Alone their artwork is pretty powerful too, having the zoomed in piece of a larger image intrigues readers into wanting to read not only one book, but the whole series. An image of all of Oliver Sacks' covers put together is included below.:
