Seems like I have to add some explaining words here ...
Book layout is a very complicated topic. If you look at that image and step away a bit it leaves a chaotic visual impression. Reason behind that is that if you want a visually pleasing look, all the paragraphs have to have a similar "density". That is defined by how long the words are, the spacing in the words (kerning, ligatures, font), and the spacing between the words. Latter is all across the board, even changes within the same paragraph! LaTeX has all that typesetting knowledge included, and it will actively hyphenate words to accomplish its goal. I see exactly one word being hyphenated there.
Another thing that stuck out immediately was the font selection for the all uppercase paragraph. Some fonts are just not made to be used that way and this is one of them. These curvy uppercase letters are nice to start words, but used together it is ... ugh.
Last is that leftover sentence at the top of the right side. It "validates" the separator image, so this is somewhat of a pro/contra mixed bag situation.
Professionals could probably say even more about all this, I just used LaTeX for a couple years more often and these are things I learned (to see) on the way.
