First of all, CUTE shop. You will definitely sell, sell, sell.
Secondly, I am NO EXPERT.
Okay, No EXPERT disclaimers down...Here's my two cents.
Fill up at least 24 slots.
Switch to white backgrounds and back up a little.
Fill up your 13 tag lines and make sure they coincide with your titles
Stick at least one link toward the bottom..maybe back to your shop page?
Here is a link that may help you with your tags:
