My photography skills are pitiful, so take my advice for what it's worth, but... I have to agree with the others - your photos aren't great. The jewelry is Gorgeous! but the photos are bla & boring. The jewelry doesn't stand out. A different color background might help. I didn't notice the pictures being fuzzy, they just don't pop. If I'd been a real shopper, I'd have landed on your page & immediately thought "boring" & moved on due to the bla-ness of the photos.
Your descriptions are great though & I didn't notice any spelling/grammar errors in the few I looked at. Good job!
