[wp-review]

Strengths:
+ Excellent main title matches perfectly with the background
+ The background suggests calmness and balance to readers
+ We like the simplicity of the cover

Weaknesses:
– I would remove or reduce the main title's font outer glow effect, this would increase the readability of the title and the background would still match perfectly thanks to the right positioning
– The author's name is completely misplaced and unreadable. Aligning the author's name with the background doesn't add any value to the cover
– The points on the cover are unnecessary, it is part of the blurb or description which could be placed on the back cover (we would reposition the author's name here in a more visible way)
(edit this section was already removed on the hardcover version of the book, which feels much better)

The overall feeling is the cover is good, with minor changes it could be a great cover.
