As most people are going to tell you, you are in a very saturated market on etsy. And you just opened. The image above needs a little work. I would make sure you are really capturing the beauty of your items with focusing and brightening up your images. Include specs of the entire piece not just a portion of the earring.
Tags really need to be 2 and 3 words. What words would a buyer use to find your item?
And lastly, keep adding more items. The more items you have listed the more chances you have of being noticed.
Just out of curiosity I searched for beaded earrings and over 370K options came up. So it's a tough market out there.
I personally love your jewelery, its simple and beautiful!
