I just took a quick look, and keep in mind I'm not an expert by any means, but my first thought is that you need to brush up on your titles.
Read up on everything you can about Etsy's Relevancy search parameters. Sign up for all the Etsy newsletters, go to SaSSy Critiques Team and ask for their Critique, which will be indepth.
What I've learned through reading and more reading, is that the first three words in your title are what the search engines pick up on first.

You should add more items to your shop, also. Give people more to look at and browse through.
Add links to your shop in your description that keep a potential customer right where you want them.
Your pictures are okay, and again I'm no expert, but I found that creating a whitebox entirely changed the look of my pictures. You can google whitebox or look on YouTube, they will give good detailed instructions. I used an old box, cut out the side and lined it with 8-1/2 x 11 paper...works perfectly at no cost.
Good luck, it takes a lot of work. I'm constantly tweaking things...my titles, my tags, my descriptions, my photos. I've seen a good increase in traffic and can't complain about my sales, other than I wish I could live off of this!!!
