Hi Stephanie. Your paintings are beautiful. Just my style actually.
You should add an about page and elaborate more about yourself and what your work is about.
Since your painting are so small, potential buyers might not know exactly how to use them or where to put them. I would suggest framing them and take a few staged pictures on how they would best be presented. Small pictures are usually seen as part of a mini gallery/ wall collage of a few small- medium items to add interest to the space.
The small size may also be great for someones house that has a blank space on their wall but it is too small for average sized art.
Hope this helps and don't give up. Etsy selling is like fishing. You need a luring picture and then great detail to snatch them up.
