My book Cover

This is my book cover. I used black and white color for my cover book. My topic is about Etiquette - Business behaviour.

Black and white represent for formal and mystery. I used Courier New and Rosewood Std. The Courier New is very easy to read and the Rosewood Std make me feel formal and secret. The picture represent the path to the success target. But I still feel it miss some thing...

What would you recommend me???
