There is a lot you can learn from one good photo...

I told Kim a few weeks ago that she didn't have enough book storage to really pull off a cool design look using books.  (see this post)

I came across this photo today- (designer Jason Oliver Nixon) and thought- now here is an example where there is a large enough quantity to have the books look great.  I also love the incorporation of decorative elements sprinkled throughout.  Notice too the area above the bookcase.  This is sometimes an area where people tend to struggle.

I also liked the cluster of wall decor.  The variety is terrific- with common elements of sepia tones and red. 

The third thing I would like you to notice in the photo below is the wall color.  Dark brown works great here.  Dark brown, in my opinion rarely works great.  But I like it here.
