The reflection on the table and the shadow of the crackers makes you wonder where to look next. Looks like you used a flashlight or something to make the near crackers bright and interesting.. and it does but it also confuses things with the odd shadows.
good idea, not so satisfying, but I can't quite put my finger on what it needs... sorry. Maybe the foreground is a little empty? Maybe I want a whole cheez-it as the subject? Dunno. Technically pretty good. Maybe the wood grain is too pronounced and distratcting?
