Hi!
The shop looks very well and cohesive. I like your pics as they are nice and bright, and the products can be easily seen in their details. I also like the style you chose for taking the pics, with the white net effect underneath. :)
I noticed though that you don't use all five pictures available for each item, and also there are no pictures showing how your earrings would look when worn. People like to see how the item is going to look on them once worn, so maybe you could add pics of the earrings worn by a real person (that would be the best), or by a head-shaped jewelllery display, or even just hanging from an object like a cup or a vase, to show the effect.
Also, you could make a better use of the tags by putting words together like "black and red" or "bohemian earrings" as the single word will still come out in the search - and generally speaking a "phrase" is always better as far as the search goes, than single words. For me the best way to come up with tags is to think what would I put in the search if I was looking for something like that?
Finally, yes, I agree with Scott Board and Twisted Pixie - you need a banner for your shop as it is the first step to brand your shop, make a statement and be remembered by visittors and customers - even more than a name in fact as people tend to remember visual elements more than names or words...
Hope this help, and good luck with your Etsy shop! :)
