Great shot of a couple of books and I like the way in which the back ground sits in the shot but not the most adventurous of shots when it boils down to it, albeit though you have pulled this one off well.
I think you misunderstood the challenge itself. You were not supposed to take a shot of a book title text, but set up a photo to represent a book title. If this was done as a joke, than ignore my comment above. Good use of shalow depth of field. I don't like the way you cropped it - it is too tight on the right. Focusing is also a bit off on the right side. The background fits the subject well.
It's a great idea for "book titles". You should have taken a picture of a real dummy in photograpy (eg me :p) not just books!
Your picture is good, nice out of focus bookselfs..
Whereas I like the idea here, I'm not sure about the actual implementation. It's a bit dull - flat objects placed flatly in a long, flat frame. If your theme is to present badness (I don't mean that this shot is particuarly bad) in photography, it might have been more effective to have chosen an obviously bad example of photography and had the books as a lesser element. 4
