Simplicity makes this cover successful. The use of the color white gives it the feeling of God. The creator made it so that the word God is in all caps and it bleeds of the cover, which implies the immensity of God. Also the text is placed high on the cover, implication of heaven.
This cover is successful because there is a good use of hierarchy and imagery. The image of Nelson Mandela is the first thing you see which let’s you know that the book will be about him.
This cover is not successful because there is too much SHIT going on. The type chosen, embossed type, terrible placement of type, the different sizes of type on the title, and just overall inconsistency. I have to say I really hate this cover. I’m done talking about it.
