You only sell to the US - however, only 65% of Etsy visitors are from the US. That's already 35% of potentially lost sales right there.
Your photos are quite gray and could really use simple brightening or curves adjustment in a graphic program (GIMP, fotofuze and many others are free to use). Gray photos just don't look appealing on Etsy, with its boutique-quality crisp, white photo standard which a lot of other vintage sellers adopt.
Some of the listings I clicked on didn't have measurements. A lot of listings lack many other searchable keywords in titles and tags.
You NEED to have good SEO and appealing photos to sell on Etsy, there's just no way around it. There is no point in wasting time promoting your shop or items before you get those things sorted out, really.
Look at how appealing this photo is - would you not want to click it? that's why this shop has so many sales!
