A lot of people are in the same boat. Do a search for threads on promoting your shop and you will find a lot of advice.
I went to your shop and I can't see what's in the framed prints well enough. See what other shops do about providing a print and framed option.
I'm not doing anything to promote myself. I opened my shop just to have a place to put my quilts but there are 25,000 quilts on etsy and no one was looking at mine. So I started putting in estate sale finds like vintage linens, hankies, patterns and housewares. Now I'm getting more views and I've sold some hankies and a pattern. You need more items in your shop and whether you want to stick solely to your type of art or you want to branch out, that's a decision you will have to make. A lot of people find that they have to branch out.
