Hi Megan,
Wonderful store! I would only recommend 2 things:
1. Try to avoid any special characters like this ****** in your intro copy or product description copy. The reason: RSS Readers and Google Base have trouble interpreting that info and either ignore products and don't display updates or display them in a very strange way.
2. We use product images for promotional purposes and prefer to use those images that don't have any writing on them. I see some of your images have name of your Creator Exhibit on them. The way you've done it at the bottom is not too bad. Sometimes people put that name right across the product image. It abstracts the view of their product and makes it impossible for us to use those images for Facebook or Google ads etc.
I would suggest not to put any writing on the product image at all for the reasons I mentioned above.
Hope this was helpful.
Good Luck and Happy New Year!
