The owner really likes reading.. one book :)

Thanks - that is a lot better. Really appreciate the comments.

Unless these books are all volumes of a single encyclopedia set (I want that encyclopedia, wow xP), you should probably vary them up a little. Make some of them differ in colour, make some a pixel shorter or taller, give some of them their gold bits in different spots.

Here's an edit to change the sizes, markings, and colours a bit, using only the reds you already have in the image.
