Geometric Sherlock

Here is my last design for Graphic Design 3.  HOORAY! I'm finally done with that class!!!  I grew a whole lot, but I'm glad to be headed towards a break, though I'm having more trouble then I can express with actually relaxing.  I have this thought in the back of my mind that I'm not quite done yet, even though I am in no mood to do anything productive—academic wise anyway.
Anyway, I am obviously getting distracted (another quality that is consistent with my newly–freed, brain–dead–self).  Even when I began this design, I was getting rather frustrated and ready to be done.  I wanted to try a more abstracted illustration and came up with this design.  Not sure how it works, or if it even represents the book / target audience well, but oh well, it's done now!

Feedback welcome, I am thinking about just scrapping this piece and trying something different...
