Amy:
You have a great shop. Your photos are near perfect. I especially love this little guy and would suggest you do more kinds of birds:

You've made six sales in just three months, and that's really good. The bane of Etsy existence is being patient and doing whatever you can to make sure people find your shop.
Join teams. Favorite other people who will favor you in return. (I just hearted some of your things and pinned two more to Pinterest.) Make friends with other Etsians and, above all, make treasuries to feature others who will eventually also feature you.
Etsy has a kind of karma about it where, if you give others what you want them to give to you (attention, hearts, feedback, sales), eventually they'll recognize you and do the same with your shop.
Best of luck, sweetie!
