Your upper-left hand corner looks like it needs something. Put a painting there or your logo. The links along the left side seem oddly indented too far in. I'd remove the bullets as they don't really add anything to the site design.
You could change your bookmark statement into a simple button along the top.
The site looks pretty good overall. I would move pictures higher on the pages tho to show them off more. Make some of your big sales text smaller. Big text is OK for a site that sells books...but
Pictures sell pictures :-)
