Wow! The good news is your photography looks very impressive and professional, so kudos on getting that so perfect! The ordering process is also explained very well, though you can always fill in an faq on each item to be 100% all the customers' questions are answered.
I do think you need to fill in your announcement and shop policy sections though, just to help it feel like there's an actual person behind the shop - one who cares about and regularly interacts with the customer.
I'd also use your shop tools to take a look at your tags to see which ones are actually performing well for your and which ones don't seem to get too many hits. It's very easy to switch them up for a few days just to see if any others work better; you can always change them back if you don't :)
There's also a very interesting post in this same group which deals with item categories, specifically adding your items into as many as possible. I'd give this a read too, as again it's something that's very easy to experiment with for a short time to see if you get any results.
Hope some of this helps :)
